5V / 3A Regulator

5 V 3 A regulator

This regulator power supply schematic diagram is the same as the previous 5V 10A regulator circuit with a little modification and have the ability to supply less current up to 3 amperes at voltage of 5V.

The circuit is built from a complete 5V regulator IC LM 109 series from National Semiconductor. While for the current amplifier using a PNP type transistor MJE 370.

5 V / 10 A REGULATOR Parts list :
R : 1 ohm 3W, 2 ohm 5W
C : 0.22uF, 10 uF
Semiconductor : LM109 K, MJE 370 ( PNP )

Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.
