Here we are designing one variable or adjustable power supply circuit using the LM317 adjustable voltage regulator.
The LM317T is an adjustable 3-terminal positive voltage regulator capable of supplying different DC voltage outputs.with currents of about 1.5 amperes.This voltage regulator can be used to get output voltage from 1.2 volts to 37 volts.We can use lm317t for dc to dc voltage regulator also.For that, we need not the rectifier part shown in this circuit.
