1. A voltage regulator, comprising:
a first portion configured to receive a first supply voltage and to output a first current drawn from the first supply voltage by a load;
a second portion configured to receive a second supply voltage, the second supply voltage being received from a different input supply than the first supply voltage; and
a current control circuit configured to, responsive to a load current corresponding to the load meeting a current sharing point, initiate current sharing of the load current between the first supply voltage and the second supply voltage; and
wherein the first portion includes an error amplifier having an output coupled to a gate of a pass transistor and directly connected to the current control circuit.
