12 Volt 2 Amp Power Supply Circuit Diagram. It has short circuit protection thermal overload protection. The 220v to 12v dc power supply is build to convert ac input to 12 volt dc output.
12v dc power supply schematics. My son builds a simple first 12 volt power supply circuit for a 12v solar pump. Datasheet for lm78xx if you are going to pull out about 1 amp from this power supply you will need a heatsink for the regulator otherwise it will generate very high temperatures and possibly burn out.
Disadvantages of a transformerless power supply circuit.
