CPC classification number: G05F1/56

Abstract: A voltage regulation circuit includes a voltage regulator that is configured to provide a stable output voltage based on an input voltage; and a control circuit, coupled to the voltage regulator, and configured to provide an injection current to maintain the stable output voltage in response to an enable signal provided at an input of the control circuit transitioning to a predetermined state and cease providing the injection current when the control circuit detects that a voltage level of the output voltage is higher than a pre-defined voltage level.
