5v dual power supply


Posted on Feb 5, 2014

The circuit is using a 230V AC OR 110V AC to 9V-0-9V step down center tapped transformer to step down the mains voltages. Four 1N4001 diodes are used for rectification of the AC voltage to DC. A 2200uF / 25V electrolytic capacitor is used the filter the voltage coming from the diodes and other capacitors are used for decoupling.
