Application of zener voltage regulator

There are some important applications of zener voltage regulator are given below,

• The zener voltage regulator is used in the emitter follower regulator.
• It is used with a small load current range over which the output DC voltage remain constant.
• It is used to regulate or vary the output voltage of the circuit.
• It is used in analog and digital circuits requiring precision references.
• It is used in source and sink circuits current.
• It is used to adjust voltage or current linear and switching powersupplies.
• It is also used in error amplifiers.
