Advantages of Zener diode shunt regulator are given below:
For wider range of load currents and input voltages the Zener diode shunt regulator provide a better regulation.
It gives higher current capability.
The Zener voltage regulator is very economic.
It requires only two or three components.
It has a very simple circuit.
Disadvantages of Zener diode shunt regulator are given below:
Internal impedance of the Zener shunt voltage regulator circuit is high.
The voltage regulation is poor.
The output voltage in Zener shunt voltage regulator is not adjustable because the output power of Zener shunt regulator is depending on Zener voltage. It means VO = VZ.
The Zener shunt voltage regulator cannot be used for large load current.
Zener shunt voltage regulator has poor efficiency for heavy loads because a large amount of power is wasted in Zener diode resistance (R2) and series resistor (RS) in comparison with load power.
The output voltage of Zener regulator slightly changes due to Zener resistance
In Zener shut regulator changes in load current produce changes in Zener current. As a result, the output voltage also changes.
