ABSTRACT:
A regulator circuit and a method for compensating for sag in the output signal of the regulator circuit. A first comparator is coupled to an input of an oscillator, which oscillator outputs a clock signal and a ramp signal. In accordance with a feedback signal from the output of the regulator circuit, the clock and ramp signals of the oscillator are reset if the output signal sags to an undesirable level. The clock and ramp signals can be reset between active edges of the clock. The reset clock and ramp signals cause the regulator circuit to increase its output voltage to reduce the sag.
