Chapter 6: Voltage Regulator - Ajlon Tech
www.ajlontech.comA feedback voltage obtained from voltage divider R 1 and R 2 is applied to the op-amp’s non-inverting input and compared to the Zener voltage to control the drive current to the transistor. The current through resistor R S is thus controlled to drop a voltage across R S so that the output voltage is maintained.
