1V-27V 3A Variable DC Power Supply Circuit Diagram

1V-27V 3A Variable DC Power Supply Circuit Diagram
Above diagram is the scheme of variable DC power supply with output range of 1V to 17V. This power supply is used very few components, the power supply will be so easy to build. Serial power transistor which will be known and popular 2N3055, power supply has a voltage control and current. The source of alternating voltage is 24V transformer. This circuit used Integrated Circuit / IC LM723, also known as UA723 which is a dedicated integrated circuit design
