This is the circuit diagram of a dual adjustable power supply using IC’s LM 317 & LM 337. LM317 is able to deliver a maximum of 1.5 A at a range of 1.2 V to +30V.

What is LM317 adjustable power supply?

Our LM317 Adjustable power supply is ready. Now we can connect any small DC load like LEDs, DC motors, etc at the output. The maximum current limit for the circuit is 1.5Amp and the Maximum output Voltage is 12Volt.

What is a variable DC power supply IC LM317?

With the help of this variable DC power supply, the output voltage can be varied from 1.2V to 30V at a current of 1A. This circuit can be used as reliable DC source and acts as a replacement to batteries. It is important to attach the voltage regulator IC LM317 to a heat sink as it tends to get hotter during operation. Note

How does a variable power supply work?

The output voltage range is controlled by connecting a 5.1KΩ pot at the ADJ pin of the regulator. The DC signal then passes through a smoothing capacitor of 100μF before going on towards the output. A Variable power supply can be used in applications such as applying a variable voltage to DC motors.

What is a variable DC power supply?

For smaller voltages, we normally use batteries as a reliable source. Instead of using batteries, which have a limited lifetime, a variable DC power supply can be used which is implemented in this project. It is a robust, reliable and easy to use variable DC power supply. The working of the circuit is as follows.
