Last Updated on: March 4, 2025 by Apichet Garaipoom

0V to 12V 3A Adjustable power supply using LM350

In a normal circuit, the general LM350 regulator has a start voltage of 1.25V. But this circuit is special that start of 0-volts. We use only one IC and a few other components. So cheap and easy for you. Read more

Experiment with Parallel Transistors for More Current

Last Updated on: April 12, 2025 by Apichet Garaipoom

Let’s learn how to use several small transistors in parallel to increase the current so that the transistor can drive bigger loads. Read more
