7812 Voltage Regulator Circuit Diagram. The ic belongs to ic 78xx voltage regulator family. We only need to use two capacitors one on the input and second one on the output of 7812 in order to achieve clean voltage output and even these capacitors are optional to use.
The second board is for the transformer the board contains the base for the primary fuse and one on off switch for 220v mains voltage. The 7812 voltage regulator ic is ease of use and available in very low cost.
