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.
