ABSTRACT:
A voltage regulator includes a first multi-gate transistor, a differential stage, a second stage having a second multi-gate transistor, and a pass transistor to apply an output voltage and output current to a device load. Based on a feedback voltage associated with the output voltage, the differential stage modulates a bias voltage applied to a control electrode of the pass transistor. A first gate of the second multi-gate transistor generates a nominal bias current for the pass transistor, and the second gate adjusts the bias voltage based on an output of the differential stage so that transients in the regulator output voltage resulting from sudden changes in current drawn by the device load are reduced.
