1. A device comprising:
a supply node configured to receive a supply voltage;
an output node configured to provide an output voltage to a load circuit, the output voltage being based on the supply voltage;
a plurality of switching stages coupled to the supply node and to the output node;
a sensing circuit coupled to the supply node and configured to provide at least one sensing signal based on the supply voltage; and
a driver circuit coupled to the sensing circuit and to the plurality of switching stages,
wherein the driver circuit is configured to receive the at least one sensing signal and to provide a drive signal to the plurality of switching stages, and
wherein the driver circuit is further configured to:
provide the drive signal based on the at least one sensing signal exceeding or failing to exceed at least one reference voltage level, and
selectively bypass a selected number of the plurality of switching stages based on the drive signal thereby varying an output voltage level at the output node.
