12V to 8V converter using LM7808 IC. The circuit is very simple using only three components. The heart of the circuit is a LM7808 fixed voltage regulator IC. Its a good IC with many build in features like thermal overload protection, short circuit protection, safe area protection etc. The output
current is upto 1A which is suitable for most electronic devices. The input voltage can be any from 12V to 35V DC. But it is adviced to use big heat sink for voltage above 20 volts. The input voltage source can be a 12 volt battery or any 12V to 35V output transformer with 2A current ratings. A 2A bridge rectifier for converting AC to DC and a electrolytic capacitor will be required with the transformer.
