1. A system comprising:
a voltage regulator operable to provide an output voltage at an output of the voltage regulator;
a current supply coupled to the voltage regulator and operable to provide an additional current to the output of the voltage regulator; and
a power management system, coupled to the voltage regulator, operable to:
set a voltage range that is associated with resetting the voltage regulator to a first range during a period in which the voltage regulator switches from a low power mode to a high power mode, wherein the first range extends from a first low threshold to a first high threshold; and
set the voltage range to a second range after the voltage regulator switches to the high power mode, wherein the second range extends from a second low threshold to a second high threshold, and wherein the second range is narrower than the first range.
