ABSTRACT:
A circuit is designed for regulating a power supply voltage. A regulator circuit (26) compares a power supply sample voltage VAR.sub.1 (34) and a reference voltage VREF (20) and corrects the power supply voltage VAR.sub.0 (30). The regulator circuit rate for correcting the power supply voltage varies with the regulator circuit power consumption. A circuit (160), responsive to a control signal (164), changes the regulator circuit power consumption.
