Adjustable Dc Voltage Regulator Circuit Diagram

It can supply greater than 1 5 a at the output.

Adjustable dc voltage regulator circuit diagram. Generally electronic circuits using tubes or transistors require a source of d c. By this high current adjustable dc voltage regulator circuit output load can connected upto 10 a load. The core of the circuit is 723 voltage regulator integrated circuit. This is 1 25 v to 32 v 10 a voltage adjustable regulator circuit.

Well this is a collection of voltage regulator circuits using the lm317 ic which is an adjustable voltage regulator. In this project we are going to design a simple adjustable power supply circuit using an lm317 voltage regulator ic. A dc voltage regulator is a device which maintains the output voltage of an ordinary power supply constant irrespective of load variations or changes in input a c. A dc adjustable power supply is an integral part of any power supply unit used in electronic equipment.

Given below is the diagram of a 1 2 v to 25 volts adjustable voltage regulator circuit using lm117 ic. Depending on the range of voltage to be adjusted there are many types of adjustable voltage regulators. A darlington pair q2 q3 boost the current to give 1a output. Lm317 is a positive voltage regulator with an adjustable voltage range from 1 25 v to 37 v.

The adjustable pin is connected with the two external resistor and connected with the vout pin of the ic. Two of the most commonly used ic s are the lm317 and lm117. The minimum voltage adjustment for this regulator ic is 2 volts above v. Adjustable voltage regulator circuit using lm317.

Lm317 is a three terminal adjustable regulator from national semiconductors and it s input can range up to 40 volts. Working of lm317 voltage regulator circuit. It serves as an interface between a wall outlet and common power electronic equipment. This voltage regulator circuit is very simple.

In most of the applications due to irregular loads the output voltage produced has fluctuations in it which can lead to damaging loads. Output current is 10 a of this circuit the lt1038 is a three terminal adjustable voltage regulator which is capable of providing of 10a output. The capacitor c1 used for the filtering of dc input voltage and further fed to the vin pin of the lm317 voltage regulator ic.
