Variable Power Supply Using LM723

Ads Below The Title
Using LM723 regulator can be designed a very simple variable power supply circuit which can provide a maximum current up to 2A and a variable voltage between 2 and 25 volts.This 25v variable power supply is designed using a LM723 regulator and a few common electronic components.Input voltage must be between 28 and 37 volts. Mj3000 transistor must be mounted on a radiator for heat dissipation.
