The AMS1117 is a common voltage regulator that comes with both fixed and customizable voltages. It is a 3-pin device mainly used to drive load under 1A. The output voltage ranges from 1.5V to 5V. When it works at maximum current, it results in a low dropout voltage of 1.3A. I suggest you read this post all the way through, as I’ll be discussing Pinout, datasheet, features, and applications of this tiny device AMS1117. Let’s jump right in.

Introduction to AMS1117

• The AMS1117 is a common voltage regulator mainly used for high-efficiency linear regulation and post-regulation switching supplies.
• This 3-pin device is also used as a battery charger and comes with an output voltage range from 1.5V to 5V. It returns a low dropout voltage of 1.3A when it operates at maximum current.

• The AMS1117 series of voltage regulators comes with both fixed and adjustable voltages and are constructed to support up to 1A current. The dropout voltage is 1.3V which decreases at low load currents.
• The current limit is applied to the power source circuitry and regulator to compensate the stress when this regulator comes across the overload situations.

• This regulator is also used in some cases to obtain a negative voltage.

AMS Datasheet

Before installing this device into your project, it’s wise to go through the datasheet of the component that gives an overview of the main characteristics and power ratings of the device.

AMS1117 Pinout

The following image shows the pinout diagram of AMS1117. The AMS1117 comes with three pins as below: 1: Adjust/Ground This pin is used to adjust the output voltage. In the case of a fixed voltage regulator, it acts as a ground. 2: Output Voltage/Vout The regulated output voltage configured by the Adjust pin is achieved from this pin. 3: Input Voltage (Vin) This pin gets the input voltage that is then regulated and produced at the output voltage.

AMS1117 Features

The following are the features of AMS1117.

• Low Drop-Out (LDO) Voltage regulator
• 3- terminal Fixed/Adjustable Linear voltage regulator
• Fixed Voltage type: 1.5V, 1.8V, 2.5V, 2.85V, 3.3V and 5V
• Adjustable Voltage range: 1.25V to 13.8V

• Built-in thermal and current limiting protection.
• Output current = 1000mA
• Operating junction temperature = 125°C
• Maximum Drop-out Voltage = 1.3V
• Available in three packages: SOT-223, SO-8 Package and TO-252

AMS1117 Usage

• Used in Arduino boards to regulate 5V and 3.3V, AMS1117 is similar to other linear voltage regulators like LM317, 7805. It is commonly famous for small form factor and is available in SMD package.
• They all, however, are configured for a maximum current of 1A. It is widely applied in active SCSI terminators and power management for a notebook.
• Depending on the output voltage and package, this linear voltage regulator is categorized into many types.

• If a fixed voltage is applied at the Vin pin of the regulator we’ll get a regulated output voltage at the Vout pin. The Adj/Ground pin is grounded in this case.
• We need to add a capacitor at the regulated output voltage to remove any noise from the regulator. The circuit diagram of the fixed voltage regulator is given below.

• In an adjustable type voltage regulator, two external resistors are included to identify the regulator’s output voltage.
• You can see from the circuit diagram below, two resistors R1 and R2 are added to identify the regulator’s output voltage.

• The capacitors are added to remove any noise from the circuit.

The following is the formula to determine the output voltage that is based on two resistors R1 and R2. To find out the desired output voltage, we can choose the R1 and R2 (must be less than 1k) of our own choice.

Vout = Vref * (1 + R2/R1) + Iadj * R2

For an Adjustable type voltage regulator we need two external resistors to decide the output voltage of the Regulator.

• A reference circuit diagram for adjustable voltage is shown below, where the resistors R1 and R2 decides the output voltage of the regulator.
• The capacitor CAdj is an optional component that can be added to improve ripple rejection if required.  The other two capacitors are to filter the input and output noise respectively.

It carries remarkable load and line regulation and is available in fixed output voltages including 3.3V, 5V, and 12V. It also comes with a customized output version where you can set the output voltage as per your requirement.

Just stay with me for a little while, as in this post I’ll walk you through the Introduction to LM2596 covering the datasheet, pinout, features, and main applications of this tiny device. Let’s jump right in.

• It is also known as a DC-to-DC power converter or buck converter which is used to step down the voltage from its input supply to the output load. The current goes up during this voltage step-down process.
• LM2596 comes with a remarkable load and line regulation. It is available in both versions: fixed output voltage version with 3.3V, 5V, 12V, and customized output version where you can choose the output as per your requirement.

• This regulator is incorporated with a fixed-frequency oscillator and an internal frequency compensation method.

• Frequency compensation is applied by adjusting both phase and gain characteristics of the open-loop output to avoid oscillation and vibration in the circuit.  This is achieved with the help of resistance-capacitance networks.
• A minimum number of external components is required for this regulator that works at a fixed frequency of 150 kHz.
• It is available in surface mount package TO-263 and standard 5-pin package TO-220.

LM2596 Pinout

The following figure shows the pinout diagram of LM2596.

The LM2596 comes with a total of five pins as follows:

Hi Friends! Happy to see you around. I welcome you on board. In this post today, I’ll discuss the Introduction to 1n5820.

The 1n5820 is a Schottky diode, also known as a hot-carrier diode, capable of extremely fast switching and is well protected against overvoltage. It carries a low forward voltage drop and high forward surge capability. It is capable of high-frequency operation and comes in the DO-201AD package.

• Schottky diode is also called hot-carrier diode since in an unbiased condition electrons possess low energy on the semiconductor material.

• This low energy leads to the formation of a barrier that blocks the electrons. Due to the formation of this barrier, Schottky diodes are also called hot-carrier diodes.

• Both Schottky diode and normal diode are different in terms of voltage required to power up these diodes.
• The Schottky diode requires only 0.3V out of 2V DC source voltage, leaving 1.7V to power the diode. On the other hand, a normal diode requires only 0.7V, leaving behind 1.3V to power the diode.

The anode, made-up of metal, is always the positive side of the diode through which current enters the diode. And the cathode side, made-up of silicon material, is always the negative side through which current leaves the diode.
• The conduction is carried out between these two terminals and current flows from the anode terminal to the cathode terminal.
• The nature of semiconductor material and the metal used plays a key role in defining the forward drop voltage of the diode. Low forward drop voltage means less energy is released as heat that makes these diodes suitable for the applications where high efficiency is required.
• These diodes are widely used in the solar systems that prevent the batteries from discharging in the absence of solar heat.

The 1n5822 is a Schottky diode that comes with a low forward drop voltage around 0.525V which means it needs 0.525 voltage to conduct the current in forward biased direction. It supports a load under 3A and is an ideal pick for switching applications with low current ratings. And the 40V is the maximum repetitive peak reverse voltage Vrrm of this tiny device. Just bear with me for just 2-min as I’ll be discussing the datasheet, Pinout, specifications, and applications of this tiny little device. Let’s get started.

Introduction to 1n5822

• 1n5822 is a Schottky diode, also known as a hot-carrier diode, mainly used in fast-clamp diode switching applications. It is made up of semiconductor material and carries low forward drop voltage.
• The small voltage drop occurs across the diode terminals when current flows through the diode.

• Though both normal diode and Schottky require 2V DC source to power these components, the Schottky diode utilizes 0.3V out of 2V, leaving only 1.7V to power the diode while the normal diode uses 0.7V out of a 2V DC source, leaving 1.3V to power the diode.

• Schottky diode is also called hot-carrier diode because electrons carry low energy when they are present on the semiconductor material in an unbiased condition.
• This results in the formation of a barrier through which electrons cannot flow, the reason it’s also called the Schottky Barrier diode or hot carrier diode.

• The 1n5822 Schottky diode is constructed by the combination of semiconductor material with metal, forming a barrier.
• The metals used in this case are tungsten, chromium, platinum, molybdenum, and silicides.
• And the n-type silicon is the commonly used semiconductor material. The resulting diode carries a very low forward voltage drop and is capable of very fast switching.
• The metal used behaves as an anode or positive side of the diode and n-type semiconductor (with a colored band) is used as a cathode or negative side of the diode. In this case, the conventional current will flow from the anode metal side to the cathode semiconductor side.
• The forward voltage of the diode depends on the nature of the metal and semiconductor you pick for the formation of that diode.
• Though both n-type and p-type semiconductors are used to form a Schottky diode, the p-type semiconductors result in very low forward voltage compared to n-type semiconductors, the reason p-type semiconductors are rarely used to form the Schottky diodes.

• In Schottky diodes less energy is wasted as heat as they possess low forward voltage drop, making them an ideal pick for the applications that are sensitive to efficiency.
• Plus, they are also used in photovoltaic systems to keep the batteries from discharging in solar panels at night.

• This diode rectifier comes with two terminals called anode and cathode.
• The anode side is positive through which current enters the diode and the cathode side is negative through which current leaves the diode and current moves from the anode terminal to the cathode terminal.

 

MUR460 Working

• The working of this component is simple and straightforward. When the voltage is applied to the rectifier diode in such a way the negative terminal of the battery is attached with the n-type semiconductor and the positive terminal of the battery is connected to the p-type semiconductor material, in this condition the diode is forward biased.

• In this forward biased condition, the free electrons available in the n-type region of the semiconductor experience a repulsive force, and a large number of holes present in the p-type semiconductor also experience a repulsive force.

• In this case, the electrons due to this repulsive force start moving from the n-type region to the p-type region and the holes in the p-type region start moving to the n-type region.
• And the conduction is carried out due to these charge carriers i.e. holes in the p-region and the electrons in the n-region.
• As this conduction is the result of the movement of free majority charge carriers in the diode, the reason the current in the forward biased condition is also called the majority current.

The following figure represents the pinout diagram of the 1n5817 Schottky diode.

• This power diode comes with two terminals known as anode and cathode. Both terminals are used for the external connection with the electrical circuit.

• The anode side is positive and the cathode side is negative. The current enters the diode from the anode terminal and it leaves the diode from the cathode terminal.
• And current flows from the anode terminal to the cathode terminal. The diode only allows the current flow in one direction only i.e. from anode to cathode. It blocks the current flow from the cathode to the anode terminal.

1N5817 Features

• Exhibits small conduction losses.
• 1n5817 is highly efficient.
• Well protected against overvoltage.
• Used in extremely fast switching.
• Available in package DO-201AD.
• Contains high surge capability.

1n5817 Schottky Diode Construction

• The 1n5817 is constructed when the semiconductor material is mixed with the metal that creates the barrier.
• When the metals like chromium, platinum, tungsten, and molybdenum are combined with the n-type semiconductor material, it results in the formation of Schottky diode. The n-type semiconductor is the material where electrons operate as a major charge carriers and holes work as minority carriers.
• The Schottky diode contains two terminals called anode and cathode. The anode side is positive that is composed of metal material and the cathode side is negative that is made-up of semiconductor material. The current flows from the positive anode metal side to the cathode negative semiconductor side. Plus, the current enters the diode from the anode side and it leaves the diode from the cathode terminal.
• Both n-type and p-type semiconductor material can be used to work as a cathode terminal in Schottky diode, but n-type materials are preferred over p-type material because the later comes with low drop voltage.
• The forward drop voltage of the Schottky diode main depends on the nature of metal and semiconductor material used to form the barrier.

LM2575 Buck Converter Datasheet, Pinout, Features, Applications

Hi Guys! Glad to see you around. I welcome you on board. In this post today, I’ll walk through the Introduction to LM2575. LM2575 is a step-down voltage regulator mainly used to step down the voltage. It is also known as a buck converter and is used to drive load under 1A. In the customized output version of the buck converter, you can set the output voltage as you like better. It comes with an extremely good load and line regulation and is available in fixed output voltages with 3.3V, 5V, and 12V. I suggest you read this post all the way through, as in this post I’ll detail the Introduction to LM2575 covering the datasheet, pinout, features, and applications of this component LM2575. Let’s get started.

Introduction to LM2575

• LM2575 is a voltage regulator and simplified version of switching power supplies that carry all functions required to step down the voltage in the circuit.
• This buck converter is incorporated with an integrated switch that can support load under 1A.

• LM2575 carries an excellent load line and load regulation. It comes in two versions: fixed output voltage version with voltage 3.3V, 5V, 12V, and adjustable output version that gives the ability to pick your desired output.
• It is also called the DC-to-DC power converter employed to step down the voltage from its input supply to its output load. The current increases during this voltage regulation.
• This regulator is integrated with a fixed-frequency oscillator of about 52 kHz and an in-built frequency compensation method.

• Frequency compensation is applied to reduce vibration and oscillation in the circuit. It can be obtained using resistance-capacitance networks.
• Apart from the remarkable load and line regulation, this device comes with a manual shutdown option through an external ON/OFF pin.
• Less external components are needed for this buck converter since it works at a fixed frequency of 52 kHz.

LM2575 Features

• Fixed versions with 3.3-V, 5-V, 12-V, and adjustable output versions
• Adjustable output version with voltage range: 1.2-V to 37-V ±4% maximum over load and line conditions
• Available in two packages named TO-263 and TO-220 packages.
• Can drive load under 1A.
• Comes with low power standby mode, commonly less than 200 µA.
• Uses easily available standard inductors and is highly efficient.
• 4.75 to 40 V is the input voltage range.
• 23V to 37V is the output voltage range.

• 80% efficiency.
• Excellent load and line regulations.
• Fixed internal oscillator frequency of 52 kHz.
• TTL shutdown capability.
• Protection against overcurrent and thermal shutdown.

LM2575 Pinout

LM2575 comes with five terminals. The following figure shows the pinout diagram of LM2575. ON/OFF = I = this terminal can shut down the voltage regulator circuit with input supply current decreasing to 50uA. Its working is simple and straightforward. When the voltage available on this pin is turned below the threshold voltage of 1.3V, it results in turning on the voltage regulator. And when the voltage is turned above the 1.3V, it results in turning off the voltage converter. You can remove this shutdown feature by connecting the pin to the ground or leaving it open. In both cases, the regulator will be turned ON. VIN = I = this is the 16 number input terminal attached with the input bypass capacitor to reduce voltage transients and to provide the switching current. Output = O = this is the 3 number pin that acts like an internal switch where voltage switches between (Vin – Vsat) and -0.5V. The duty cycle on this pin is Vout/Vin. The PCB copper area connected to this pin is mainly used to reduce the coupling. Ground = three pins number 5,12 & 13 are attached to the ground. Feedback = I = this is the 7 number pin that indicates the regulated output voltage for the feedback loop.
