Abstract
A control circuit for controlling a switching regulator that converts an input voltage to a regulated output voltage. The control circuit has an input-output comparator configured for comparing a difference between the input voltage and the output voltage, and producing a first sleep signal for placing the regulator into a sleep mode, when the regulator operates in a dropout mode, and the difference between the input voltage and the output voltage becomes less than a first predetermined value.
