The project presented here is a dual output linear power supply. This power supply provides low ripple low noise DC regulated output. It is a very useful tool to power Audio, Video, OPAMP-based circuits, and projects. The circuit provides regulated +/-12V DC output @ 400mA + 400mA. The project supports AC input supply 230V or 115V. On-board jumpers are provided for AC230V or AC115V selection. Besides regulated output, the board also has provisions to output the unregulated supply using CN2.
