Introduction to 7805

Hey Fellas! We always strive to keep you updated with best and valuable information so you keep coming back for what we have to offer. Today, I am going to uncover the details on the Introduction to 7805. It is a positive voltage regulator used for providing constant output voltage over a wide range of input voltage. Before we move on, you must be clear what is voltage regulation? Voltage regulation is referred as the measure of voltage change between input and output. The IC 7805 does the same thing. It provides constant output voltage when a range of different voltage is applied at the input terminal. This component comes with three terminals called input, ground, and output. This is called positive voltage regulator because it generates positive voltage with respect to the ground terminal. Transistors and voltage regulator IC like 7805 work in a similar way with the intention of providing voltage regulation. I'll discuss each and everything related this integrated circuits, so you get a clear idea what it does, and how it is used over a wide range of applications. Let's dive in and explore what is this about and everything you need to know.

Introduction to 7805

• 7805 is an IC used for voltage regulation and comes in TO-220 version. This component belongs to 78xx series where xx defines the output voltage it generates.
• Voltage fluctuation is a common practice during the execution of many electronic projects. This component overcomes and prevents this voltage fluctuation by providing a constant output voltage at the output terminal.
• The best part is that it doesn't require any additional components to set output voltage.
• It is a compact IC that comes with a built-in protection circuit that avoids the circuits from too much heating, making it suitable for circuits drawing high current.
• The input voltage range applied to the input terminals of this IC varies from 7 V to 18 V (in some cases 7 to 35 V), resulting in the generation of constant output voltage around 5 V.
• You can see, there is a huge difference between input voltage and the output voltage that gets regulated. This difference is discharged as heat. The surge of heat generation can damage the device and affect the overall project performance.
• There are two ways to overcome this heat generation i.e. you can use a heat sink that is widely used for heat dissipation OR you can limit the input current 2 to 3 V above the regulated voltage at the output terminal. For example, you'll get 5 V at the output terminal, so it is suitable to limit input voltage within 7 or 8 V.

• Heat sink comes in different sizes based on the amount of heat that is required to disperse. It is advised to calculate the size of heat sink before you put your voltage regulator in operation.
• With the addition of heat sink, this IC can control output current at around 1.0 A.
• This voltage regulator is an ideal choice for the applications where safe area compensation, thermal shutdown, and current limiting is required.
• This device is designed with the purpose of getting constant output voltage, however, it can be coupled with external components with the intention of generating desired voltage and current.
• This IC comes with an accurate circuit which generates constant voltage so no capacitors are required to produce smooth output, however, it is advised to place 10µF capacitors in the input and output terminal to remain in the safer side.

Pinout of 7805

• Following figure shows the pinout of this voltage regulator.

• Pin 1 shows the input voltage applied to this regulator which ranges between 7 to 18 V.
• Pin 2 shows the ground terminal. Voltage regulator generates positive voltage with respect to the ground terminal.
• Pin 3 shows the output terminal where regulated voltage is obtained. Regulated voltage shows the tolerance between 1.5 % to 2 %.
• This regulator has a capacity of controlling output current around 1 A.
• It shows a voltage dropout around 2 V. It is advised to provide minimum 7 V at the input terminal in order to obtain exact 5 V at the output terminal.

Absolute Maximum Ratings

• Following figure shows the absolute maximum ratings of 7805.

• These are the stress ratings, which if exceed from absolute maximum ratings, can damage the device severely.
• Before you place this regulator in the circuit, make sure it undergoes and exhibits same stress ratings as defined by the manufacturer.
• Similarly, it these stress ratings are applied for a maximum period of time above the normal operating conditions, they can affect the device reliability.
• These ratings are obtained with a storage temperature range at around 150 °C.
• This IC exhibits a thermal resistance around 5 °C/W which is the resistance in the heat flow.

Applications

This voltage regulator is used over a wide range of applications. Following are some main applications of this regulator.

• Used in a circuit where a constant voltage is required.
• It is used in a phone charger and portable CD player.
• UPS power supply circuit and remote control extension make use of this regulator.
• This regulator is widely used where internal circuit current limiting is required.
• Safe area compensation is another advantage obtained from this regulator.
• This regulator is mainly used for generating constant voltage output, but it can be customized to use for the required current and voltage at the output.
• It is an ideal choice for the applications which support current around 1.0 A to 1.5 A which cannot be obtained without proper heat sinking.
• Safe operating area protection and thermal shutdown make it suitable for many applications involving high temperature and pressure.

Introduction to 2n3792

Hey Guys! Hope you are doing great. Transistors are the fundamental parts of the recent electronic devices. They are available in two types i.e. NPN and PNP transistors. Based on the technical aspect and utilization, both types come with different benefits and advantages. Today, I am going to discuss the details on the Introduction to 2n3792. It is a PNP (positive-negative-positive) silicon bipolar power transistor mainly used for amplification and medium speed switching. It is manufactured using epitaxial planer process and comes in TO-3 casing. I'll cover each and everything related to this transistor so you don't need to go anywhere and find all information in one place. Let's explore what is this about, its main applications and everything you need to know.

Introduction to 2n3792

• The 2n3792 is a PNP bipolar transistor which is mainly used for amplification and medium speed switching applications.
• It consists of three layers where one N-doped layer is housed between two P-doped layers.
• It has three terminals called emitter, base, and collector. All these terminals are different in terms of their doping concentrations. The emitter is highly doped as compared to base and collector terminals.
• In this transistor, base-emitter is more positive with respect to base and collector. While negative biased voltage is applied at the base terminal.
• It is a current controlled device where small current at the base side is used to control the large current at other terminals.

• In this PNP transistor, current directions and voltage polarities will be reversed as compared to NPN transistors.
• It works in a similar way to NPN transistor i.e. both are used for amplification purpose where small current at the base side is used to control the large current at the emitter and collector side, however, there is one exception, unlike NPN transistor, holes are diffused through base from the emitter and collected by the collector.
• This PNP transistor is rarely used for amplification purpose because conduction carried out by the movement of electrons is considered more valuable than conduction carried out by the movement of holes.

Pinout of 2n3792

• Following figure shows the pinout of this PNP transistor. It consists of three terminals.

1. Base 2. Emitter 3. Collector 

• Voltage is applied at the base terminal, which draws small current.
• The output current obtained at the collector terminal is highly dependent on the voltage applied at the base terminal. This process is used for amplification purpose.

Circuits Diagram of 2n3792

• Following figure shows the circuit diagram of 2n3792.

• Current at the emitter terminal is equal to the sum of current at the base and collector side. The emitter is highly doped so it exhibits more current as compared to other terminals.
• In this transistor current direction is reversed as compared to NPN transistor. In this case, current flows from collector to emitter.
• Voltage polarities are also reversed. Negatively biased voltage is applied at the base terminal in order to initiate holes reaction which is then used to control the large current at the other terminals.
• As the name suggests, this is a bipolar junction transistor where conduction is carried out by both charge carriers i.e. electrons and holes, but holes are majority charge carriers in this case. While electrons are majority charge carriers in NPN transistors.

Absolute Maximum Ratings of the 2n3792

• Following figure shows the absolute maximum rating of the 2n3792.

• These are the stress ratings that play an important role in the selection of this transistor for electronic circuits.
• If stress ratings exceed the absolute maximum ratings, they can damage the device.
• Similarly, if these ratings are applied for the maximum period of time above normal operating conditions, they can effect the reliability of the transistor. Before you pick this transistor for your project, make sure, it exhibits and undergoes same ratings as defined by the manufacturer.
• Power dissipation is 150 W and these absolute maximum ratings are taken at the absolute junction temperature around 200 ºC.
• Thermal resistance is 1.17 ºC/W which is the measure of resistance to the heat flow.

Applications

• This transistor is used for medium speed switching applications.
• It is also used for an amplification purpose.
