Simple Designing 12V 5A Linear Power Supply
This is a 12V 5A linear power supply circuit. Also, how to find resistors onside. I like to use a series of 78xx regulator ICs. Because it is so easy with a few parts. If we want 12V output. So, use 7812. But Maximum current at the output does not exceed 1A. What can we … Read more
