5V / 3A Regulator devresi

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 )
