Abstract: In embodiments, a voltage regulator has an input node to receive an input voltage and an output node. The voltage regulator has a charge pump circuit that receives a boosting control signal to boost the input voltage based on the boosting control signal. The voltage regulator further has a feedback regulation circuit configured to receive the output voltage and to provide a first operation control signal and a second operation control signal as a function of the output voltage; a phase control circuit configured to receive the first operation control signal and to provide the boosting control signal as a function of the first operation control signal; and a filter coupled to the output node, configured to receive the second operation control signal and configured to inject to or sink from the output node a charge that is a function of the second operation control signal.
