Zener as Regulator



Zener Regulator
A zener diode is sometimes called a voltage-regulator diode because it maintains a constant output voltage even though the current through it changes. For normal operation, the zener diode is reverse-biased. The output of a power supply connected to a series resistor and a zener diode. This circuit is used when dc output voltage is required. A circuit like this is called a zener voltage regulator.This circuit hold the load voltage almost constant despite large changes in line voltage and load resistance.
