Abstract:
1. A shunt regulator circuit comprising: a regulating device configured to receive an input voltage and whose degree of conduction is controllable to control production of an output voltage at a terminal; a source configured to produce a reference voltage that sets a target value for the output voltage; an error amplifier configured to produce an output signal to control the conduction of the regulating device in response to comparing the output voltage and the reference voltage; and a control circuit configured to operate the regulating device to (i) first clamp the output voltage at a first level value below the target value, (ii) then force the output voltage to reach a second level value still below the target value, and (iii) then permit the output signal of the error amplifier to control the conduction of the regulating device to produce the output voltage at the target value.
