Abstract
A voltage regulator is described. It includes an amplification stage to control a voltage level of a first gain node and of a second gain node in response to an input voltage, to activate a first and a second output stage, respectively. It further includes the first output stage to source a current at an output node of the voltage regulator from a first potential. The voltage regulator includes the second output stage to sink a current at the output node to a second potential. The voltage regulator includes a first operating point control circuit to set the voltage level of the first gain node such that a first maintenance current is sourced by the first output stage; and/or a second operating point control circuit to set the voltage level of the second gain node such that a second maintenance current is sunk by the second output stage.
