Variable power supply using IC- lm317

Description

A very well-designed power supply circuit of a regulated stable adjustable power supply using IC LM317T. LM317T is a very famous IC and is easily available in the market comes with 3 pins, supporting input voltage is from 3 volt to 40 volt DC and delivers a stable output between 1.25 volt to 37 volts DC. It is a very high-performance IC that contains a built-in current limiter, built-in thermal overload protection & safe area protection.LM317T output current is 1.5A but many other low and high current models are also available in the market.

This variable power supply is best and ideal for lab use and also for many other purposes. The output voltage is adjustable between 1.25v to 12v and the maximum output current is 1.5A. The circuit is very simple to build & contains fewer components but will give the very best results. The output voltage is adjusted by a 5.1K potentiometer. Use a good heat sink with IC.
