Abstract: A voltage regulator includes a voltage converter is configured to generate an output power supply voltage based on an input power supply voltage and an input reference voltage and provide the output power supply voltage to an external functional circuit, the voltage converter including an output terminal configured to output the output power supply voltage; and a sinker connected to the output terminal, the sinker configured to generate a sink current in response to a sink enable signal while the external functional circuit is not driven and configured to block generation of the sink current in response to an operating enable signal while the external functional circuit is driven, wherein the sink current corresponds to a load current that is to be consumed while the external functional circuit is driven.
