Abstract

A system and method to regulate voltage is disclosed. In a particular embodiment, a voltage regulator includes an error amplifier, a voltage buffer responsive to the error amplifier, and a first transistor responsive to the voltage buffer and coupled to a voltage supply source. A second transistor is coupled to the voltage supply source and further coupled to an output node. A third transistor is coupled to the first transistor and has a gate coupled to a capacitor. The capacitor is coupled to a node between the error amplifier and the voltage buffer.
