WebNov 1, 2007 · The basic operation of a shunt regulator is described below using a simplified circuit. When the output voltage drops due to a variation of the load, the voltage applied to resistors R 1 and R 2 drops. This then lowers the voltage of V 1, which is the output voltage divided by R 1 and R 2. WebSome shunt regulators can become unstable when only lightly loaded. In this case it may be necessary to preload the output with a resistor in order to maintain this minimum load requirement. Doing this modifies R LOAD(min) and it is this modified R LOAD(min) that should be used in the procedure when calculating R3 and C2. Simplified circuit
