Abstract
A low dropout voltage regulator with quiescent current reduction has a pass transistor coupled for conduction from a positive supply terminal to a regulated output terminal. A first switch is coupled to conduct the base current of the pass transistor to the regulated output terminal. A second switch is coupled to conduct the base current of the pass transistor to ground. A control circuit selects the action of the switches to select the conduction path for base current.
