1. An apparatus comprising:
a plurality of switch capacitor drivers coupled to an input supply node and an output supply node, wherein the output supply node is to provide an output voltage to one or more loads;
a controller coupled to the plurality of switch capacitor drivers and to cause the plurality of switch capacitor drivers to operate in a switch capacitor regulation mode or a linear regulation mode in accordance with a current demand of the one or more loads; and
a comparator coupled to the controller, wherein the comparator is to receive at least three inputs, and wherein the at least three inputs include: a version of an output voltage, the output voltage, and a reference voltage.
