Zener Shunt Regulator. However without proper components this circuit can be far more inefficient than a linear regulator. The zener diode regulator zener diodes can be used to produce a stabilised voltage output with low ripple under varying load current conditions.
The zener diode regulator zener diodes can be used to produce a stabilised voltage output with low ripple under varying load current conditions. Zener diode shunt regulator if there is no load resistance shunt regulators can be used to dissipate total power through the series resistance and the zener diode. By passing a small current through the diode from a voltage source via a suitable current limiting resistor rs the zener diode will conduct sufficient current to maintain a voltage drop of vout.

A zener diode differs from normal diodes in that its breakdown voltage is well defined during fabrication and it can revert from the breakdown region. Shunt regulators have an inherent current limiting advantage under load fault conditions because the series resistor limits excess current. The zener diode shunt regulator when you know the level of the supply voltage and you have a small load using a zener diode as a regulator can be a great option. By passing a small current through the diode from a voltage source via a suitable current limiting resistor rs the zener diode will conduct sufficient current to maintain a voltage drop of vout.
