ABSTRACT:
A switching mode voltage regulator circuit that operates at reduced quiescent current levels is provided. The voltage regulator preferably includes a control circuit and a switching element that connects and disconnects filter circuitry from the control circuit. An error amplifier in the control circuit is placed in a micropower operating state when the regulator is in standby mode to reduce quiescent current.
