12v 5a power supply using lm338


Posted on Feb 5, 2014

A 12V power supply is a very essential and useful supply for Lab because it is used by a huge list of electronic circuits and devices. So you can build a 12V power supply circuit according to your ampere requirements. voltage regulator IC available in 3 terminals. This IC also contains many built in features like current limit constant with temper

ature, thermal regulation, short circuit protection etc. The voltage of the LM338 is adjustable between 1. 2 to 37 volt. But you can also use it on your desired fixed voltage between 1. 2 to 37 volt. The circuit mentioned here is built to take 12V & 5 ampere fixed output from this IC. The IC will become hot during the operation due to which a suitable heatsink will be required.
