Patent ID: 8315111

Claim:
A regulator circuit comprising: a reference voltage generator circuit that is configured to generate a reference voltage at an output of the reference voltage generator; a first gate driven amplifier having a gate coupled to the output of the reference voltage generator circuit and configured to output a first regulated output voltage in response to the reference voltage being applied to the gate of the first gate driven amplifier; a second gate driven amplifier having a gate and configured to output a second regulated output voltage in response to a voltage applied to the gate of the second gate driven amplifier; a switching circuit configured to, in response to an enable signal, couple the output of the reference voltage generator circuit to the gate of the second gate driven amplifier; and a pre-charge circuit configured to mitigate voltage draw from the gate of the first gate driven amplifier to the gate of the second gate driven amplifier, by charging the gate of the second gate driven amplifier in response to the enable signal.
