This is a low current transformerless power supply for small applications. The capacitor reduces the high volt AC. D1-D4 rectifies AC to DC and second reduces ripples. The Zener diode is used to get regulated DC output.
The Zener value can be changed to get other output voltages. This power supply is suitable when designing for an application that requires low power and where cost and size are of great consideration as the expensive and bulky transformer is eliminated in this type of power supply. All the components in this circuit are sized so that the circuit can deliver 12 volts and 30mA of current at the output to the load.
