Abstract
A voltage regulator includes an error amplifier configured to amplify a difference between a feedback voltage and a reference voltage. The regulator also includes an N-type metal-oxide-semiconductor (NMOS) driver circuit. The driver circuit includes an n-type field effect transistor. The driver circuit is communicatively coupled to output of the error amplifier. The regulator further includes a feedback circuit communicatively coupled between the NMOS driver circuit and an input of the error amplifier to provide the feedback voltage.
