Performance of shunt voltage regulators based on Zener
exploit the avalanche effect for use in ‘Reference voltage ‘regulators. A Zener diode can be used to generate a fixed voltage by passing a limited current through it using the series resistor ( R3 ). The Zener output voltage is not seriously affected by R3 and the output remains as a stable reference voltage. But the limiting resistor R3 is important, without which the Zener diode will be... (a) Zener diode as shunt regulator; (b) V-I characteristics of Zener diode. any current that would normally pass through the load when it changes and the demand for current decreases.

Zener Diode Voltage Regulators 2 The forward bias region of a Zener diode is identical to that of a regular diode. In the reverse bias condition the Zener diode is an open circuit and there is only a …... Zener diode voltage regulator Often in the development of electronic circuits it is required that voltages be limited in some manner to avoid circuit damage. Furthermore, the limiting or clipping of voltages can be very useful in the development of wave-shaping circuits. A typical clipper circuit is shown in Figure 2. In this circuit the output voltage can never be greater than 3 V. The ideal

The most common voltage reference is the Zener diode (). A Zener diode is a diode where the avalanche reverse breakdown behavior has been optimized and quantified such that the diode can be operated safely in that region.

The voltage regulation is given by the same expression as or the simple Zener diode regulator: However, the variation of the Zener current result from the variation of the base current which is ? times less than the possible change of the load current.... Line Regulation Since the Zener diode in a shunt regulator has some small (but non-zero) dynamic resistance r Z, we find that the load voltage V O will have a small dependence on source voltage V S. In other words, if the source voltage V S increases (decreases), the load voltage V O will likewise increase (decrease) by some very small amount. Q: Why would the source voltage V S ever …

- voltage of the Standard regulator is the highest (worst) of the three types. The ground pin current of the Standard regulator is very low (an LM309 can supply 1A of …
- The Zener regulator (resistor R and Zener diode form a simple Zener regulator) has to supply only the base current of the transistor. The emitter follower voltage regulator is, therefore, much more efficient than a simple Zener regulator. Limitations The output voltage cannot be maintained absolutely constant because both VBE and Vz decrease with the increase in room temperature. Further, VBE
