Abstract
Mechanisms are provided for either power gating or bypassing a voltage regulator. Responsive to receiving an asserted power gate signal to power gate the output voltage of the voltage regulator, at least one of first control circuitry power gates the output voltage of a first circuit or second control circuitry power gates the output voltage of a second circuit such that substantially no voltage to is output by the first circuit to a primary output node. Responsive to receiving an asserted bypass signal to bypass the output voltage of the voltage regulator, at least one of the first control circuitry bypasses the output voltage of the first circuit or the second control circuitry bypasses the output voltage of a second circuit such that substantially the voltage of a voltage source is output by the first circuit to the primary output node.
