This is a circuit of a 12V to 5V converter using a 7805 regulated IC. In the previous article we have discussed about the circuit of 12V to 9V converter which can be used to convert any source of 12V DC to 9V DC using 7809 IC. The circuit mentioned here is also a step down DC to Dc converter like the



pervious one but it is using LM7805 IC which can provide fixed 5 volt output from any 12V DC source. The circuit is ideal to use with a 12V car battery to step down the voltage to 5 volt DC. LM7805 is an IC of LM78xx series. It has many built in features like thermal shutdown, short circuit protection and safe operating area protection. These type of ICs are commonly used in regulated power supply circuits.
