0 12v Variable Power Supply

We often require dc voltages for our experiments then why spend money on cells or rechargeable batteries why not build a power supply that takes ac 220vrms and gives required output. A power supply whether it is a battery or a switched mode ac adapter is one of the most important tools in electronics. A linear power supply continuously converts the ac to dc with a constant.

Obviously you need something to supply electricity to your electronic projects. The empty space in the pcb layout is for transformer in case of any. In the circuit with the components value makes the output voltage range of approximately 1 25 to 13 5 volts. Making your own power supply is also one of th.

Introduction the purpose of this instructable is to make a power supply that can give output of 5v constant and 0 12v variable output. A switched mode variable power supply is an electronic power supply that utilizes a switching regulator to convert electrical power.
