LM317 Variable Voltage Regulator Circuit

In this tutorial we will show you how to get the variable regulated Voltage from the LM317 IC. With a small circuitry attached with LM317 we can get variable voltage up to 37v with 1.5A max current. The output voltage is varied by varying the resistor connected to LM317’s adjustable pin.
