Abstract

A voltage regulator receives an input voltage and produces a regulated output voltage. A first feedback network compares a feedback signal to a reference signal to assert/de-assert a first pulsed control signal when the reference signal is higher/lower than the feedback signal. A second feedback network compares the output voltage to a threshold signal to assert/de-assert a second control signal when the threshold signal is higher/lower than the output voltage. A charge pump is enabled if the second control signal is de-asserted and is clocked by the first pulsed control signal to produce a supply voltage higher than the input voltage. A first pass element is enabled when the second control signal is asserted and is selectively activated when the first pulsed control signal is asserted. A second pass element is selectively activated when the second control signal is de-asserted.
