A variable 1.2 to 19 volt 5/10 amp power supply.

This project consists of a variable 1.3 to 20 volt power supply at a medium current of 5 or 10 Amps depending on the transformer connections. It contains a low cost 3 terminal regulator with a PNP series pass current boost transistor.

Details of the project are contained in the PDF link here.

A simple 5 amp dual power supply.
