A multiple input linear voltage regulator includes an output port configured to supply an output voltage to one or more processor components; a first regulating transistor operable to receive a first input voltage from a first supply and provide a first regulated voltage range to the output port; a second regulating transistor operable to receive a second input voltage from a second supply and provide a second regulated voltage range to the output port, wherein the first input voltage is different from the second input voltage; and a control circuit operable to selectively drive the first regulating transistor and the second regulating transistor based on at least a target output voltage.
