Description
A basic regulated 12 volt power supply

note
The circuit above uses a 13 volt Zener diode, and D2 provides voltage regulation. The Aprroximately 0.7 volt fully falling transistor is the junction, leaving a higher current output of 12.3 volts. This circuit can provide loads up to 500 mA.This circuit is also known as an amplified Zener diode circuit.
