Circuit of a 8V power supply using LM7808 IC. LM7808 is a voltage regulator IC comes in TO220 transistor package. This IC is packed with many built in features like short circuit protection, over heat protection, current limiting, output current upto 1A etc. The circuit is using 230V to
12V 2A tranformer, use 2A diode bridge or you can also use 4 diodes of 2A in the place of diode bridge. The IC will become hot during the operation due to which a suitable heatsink will be required.
