Lm317 Power Supply Circuit. September 8 2020 in the event we need to build a variable dc power supply that output of 1a and can adjust up to about 30v. A lm317 is a versatile device which helps an electronic hobbyist to build a variable voltage power supply quickly cheaply and very efficiently.
As the name suggests a variable power supply circuit provides the user with a range of linearly varying output voltages through a manually controlled potentiometer rotation. Variable supply basic electronics updated. September 8 2020 in the event we need to build a variable dc power supply that output of 1a and can adjust up to about 30v.

This circuit has an inbuilt bridge rectifier so i can directly supply 220v or 110v ac supply at the input of the lm317 circuit. This circuit has an inbuilt bridge rectifier so i can directly supply 220v or 110v ac supply at the input of the lm317 circuit. The circuit converts 230v 110v ac to 0v 12v dc. The lm317 device is an adjustable three terminal positive voltage regulator capable of supplying more than 1 5 a over an output voltage range of 1 25 v to 37v.
