What is a transformerless power supply. Y ou can change zener diode and change the voltage if you need 12 volt output use 12 volt zener diode instead 5 volt. The actual value of current given in table i will not be available at the output since it may vary slightly depending on the input voltage and current. As the name defines a transformerless power supply circuit provides a low dc from the mains high voltage ac without using any form of transformer or inductor.

This 12 volts transformerless power supply take advantage of the fact that a zener diode is also a normal diode that conducts current in the forward.
