Zener Diode Shunt Regulator. 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. Every diode has a maximum reverse voltage above which it breaks down the properly named reverse breakdown voltage.

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. This method uses a number of fixed voltage relatively low current regulators at various points around the circuit being supplied. A typical zener diode shunt regulator is shown in figure 3.
Every diode has a maximum reverse voltage above which it breaks down the properly named reverse breakdown voltage.
Point of load regulators the most common method of using these basic zener diode shunt regulators is the point of load regulation system. The simplest shunt regulator is made with a resistor and a zener diode. This method uses a number of fixed voltage relatively low current regulators at various points around the circuit being supplied. The resistor is selected so that when the input voltage is at v in min and the load current is at i l max that the current through the zener diode is at least i z min.
