1. A voltage regulator comprising:
an output port to supply power to a component of a computer system, a target voltage level of the power to increase if a current level of the power decreases;
an input port to receive a power state signal, the target voltage level to decrease when the component transitions to a sleep state as indicated by the power state signal; and
a feedback line to couple the output port to the input port, a feedback voltage of the feedback line to be adjusted according to the power state signal, wherein the input port is coupled to an input of an inverted logic device, the inverted logic device having an output coupled to the feedback line to reduce the feedback voltage of the feedback line when the inverted logic device is turned on.
