There are some important applications of zener voltage regulator which are given below.
- The zener voltage regulator is used to regulate or vary the output voltage of the circuit.
- It is used to adjust voltage or current linear and switching power supplies.
- It is also used in error amplifiers.
- It is used in analog and digital circuits requiring precision references.
- It is used in source and sinks circuits current.
- It is used in the emitter follower regulator.
- It is used with a small load current range over which the output DC voltage remain constant.
