Working-

This small circuit is made for DC power Supply its regulates 220v Ac into variable dc from 3v to 24 volts

Advantages-

This is smallest power supply for small circuit you can use it projects or industrial Projects

Advance feature-

I add mov and fuse resistance for safety and protect this circuit for over voltage and over current protection 

Disadvantages-

Keep away from moisture because this have no isolation and ant pure dc voltages and cant provide high amp to the circuit

Components-

-104j 400v ceramic capacitor

-25v 220 micro farad Capacitor

-1M ohm resistance 

-Bridge Rectifier 

-Mov

-Fuse Able Resistance
