Abstract
Apparatus and method relating to voltage regulation is disclosed. In an apparatus thereof, an integrated circuit includes a first differential opamp having a first gain. The first differential opamp is configured to receive a reference voltage and a feedback voltage. A second differential opamp has a second gain less than the first gain. The second differential opamp is configured to receive the reference voltage and the feedback voltage. A driver transistor is configured to provide an output voltage at an output voltage node and to receive a gating voltage output from the second differential opamp. A differential output of the first differential opamp is configured for gating a current source transistor of the second differential opamp. A capacitor is connected to the driver transistor and the current source transistor.
