3A adjustable regulator using LM350


Posted on Feb 5, 2014

This is the circuit diagram of a 3A adjustable power supply using IC LM350K. LM350K is a very rugged voltage regulator IC with features like thermal regulation, short circuit protection etc. This circuit is designed as per the application notes in the data sheet and was found to be working very fine. This circuit has improved ripple rejection and b
