Question

give the reasons why zener diode acts as a reference element in the voltage regulator circuits?

Answer 1

Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits. When connected in parallel with a variable voltage source so that it is reverse biased, a Zener diode conducts when the voltage reaches the diode's reverse breakdown voltage.

The function of a regulator is to provide a constant output voltage to a load connected in parallel with it in spite of the ripples in the supply voltage or the variation in the load current and the zener diode will continue to regulate the voltage until the diodes current falls below the minimum IZ(min) value in

Answer 2

QUESTION:-

Give the reasons why zener diode acts as a reference element in the voltage regulator circuits?

ANSWER:-

• The Zener diode is a kind of semiconductor diode which are broadly used in circuit designs of electronics as a voltage reference.

Zener diode acts as a reference element in the voltage regulator circuits because

• The Zener diode is broadly used as a voltage reference in which its reverse breakdown factor contributes to a stable voltage across the diode over an expanse of currents which flows through it. The Zener diode or voltage reference diode is an electronic element that contributes to a stable and defined voltage. Hence, Zener diode circuits are often used in voltage regulator circuits which designs where regulated outputs are required.
