6 - 12 Volt | Adjustable Power Supply Circuit

adsjust power supply
Power Supply in this article use a regulator that is composed of 2 pieces of NPN transistor. A transistor acts as a power regulator and a transistor again serves as a controller output voltage.

Power Supply has an adjustable output with a range of 6-12 VDC. The part that serves as a power regulator is Q1 TIP31. Then the controller output voltage is a voltage divider composed of R3, R4, VR1 and R2 provide bias to the base of Q2 to Q1 mengentrol power regulator. In a series of power supply is mounted 5.1 V zener diode which serves to make the minimum limit the output voltage with Q2.
