Abstract

A regulator includes a driver stage having an output port for providing an output voltage, a predriver coupled to the driver to control the output voltage provided by the driver stage, a comparator to compare the driver output voltage to a reference voltage, and a feedback element coupled between the driver output port and the comparator. The driver may include a high side transistor having a collector coupled to a collector of a low side transistor, and a current sensing transistor having a base coupled to a base of the low side transistor.
