Abstract
A voltage regulator includes an error amplifier circuit, an output stage circuit and an output feedback path. The error amplifier circuit includes a first-stage amplifier and a second-stage amplifier. The first-stage amplifier is configured to amplify a difference between an output feedback signal and a reference signal to generate a first differential signal and a second differential signal. The second-stage amplifier is configured to amplify a difference between the first differential signal and the second differential signal to generate an output control signal. The output stage circuit is coupled with a first power terminal, and includes a switch. The switch is configured to generate an output signal at an output node according to the output control signal. The output feedback path is coupled with the output node and the error amplifier circuit, and is configured to generate the output feedback signal according to the output signal.
