Another good designed circuit of a variable stabilized power supply using LM350K. LM350K is a very good voltage regulator IC it has many built-in features like short circuit protection, thermal regulation etc. The circuit given below is designed to provide a stable voltage between 1.2V to
25V and provide 3A current.The output voltage can be adjustable through 2.7K pot. This power supply is ideal where you want high current with regulated voltage. The circuit is very easy to build and all parts are easily available in the market.
