LM317T Voltage Regulator with Pass Transistor

All about what's inside AC Power Adapters. First I break them open, then I disassemble the components, and then I back engineer their electrical and electronic design. Learn to identify, test, and repair AC power adapters. They power your computer peripherals, cell phones, battery chargers, and gadgets? The purpose of wall transformers is to step-down residential AC voltage to a much lower voltage, typically between 3 and 36 volts. Some adapters have an AC voltage output while others have a DC voltage output. Find out if your ac adapter is good or bad.
