ABSTRACT:
Circuits and methods are provided for low drop-out operation of switching regulator circuits that include a switching transistor and an output circuit adapted to supply current at a regulated voltage to a load. The circuits and methods generate a limiting signal that allows the switching transistor to remain in a continuous conductive state for a predetermined number of oscillator cycles. The predetermined number of oscillator cycles is preferably set by a counter that initiates a signal that turns the switching transistor OFF.
