Make a 5V 2A Power supply by IC 78S05 simple circuit at home

How to make a 5V 2A simple electronic power supply using IC 78S05 at home to charge cell phon battery.


Today we are going to learn how to make a simplest 5 volt 2Amp DC simple power supply which can be used in various application like cell phon battery chargers like in Tabs ehich requires high current, LED Drivers which require less than 6 volt and high current , can bye used to charge a cell phon batttery using solar panel e.t.c. at home.

This circuit is extremely simple and easy to make, simple to use and with very less component used.

The main component in this circuit is IC 78S05 which is a Voltage regulator 5V / 2A DC. The quality of current is high and noise is low.

The circuit will work without any extra components, but for reverse polarity protection a 1N5402 diode is included for safety at the input, extra filtering and removing any ripple is being done by capacitor C1-220uF 50V.

Circuit diagram:

The output stage includes a capacitor C2-47uF 25V for extra filtering.
