Abstract

In certain aspects, a voltage regulator includes a pass n-type field effect transistor (NFET) coupled between a first voltage rail and a second voltage rail, and a pass p-type field effect transistor (PFET) coupled between the first voltage rail and the second voltage rail. The voltage regulator also includes a first amplifier having an output, a first switch coupled between the output of the first amplifier and a gate of the pass NFET, a second amplifier having an output, and a second switch coupled between the output of the second amplifier and a gate of the pass PFET, a third switch coupled between the gate of the pass NFET and a ground, and a fourth switch coupled between the gate of the pass PFET and the second voltage rail.
