Abstract
Disclosed is a voltage regulator including a power supply terminal and an output terminal. The voltage regulator includes an NMOS transistor including a drain electrode connected to the power supply terminal, a gate electrode, and a source electrode connected to the output terminal; a first regulating circuit including a voltage divider circuit connected between the output terminal and ground, and configured to generate a feedback voltage based on the output voltage of the output terminal, and an error amplifier including a first input terminal, a second input terminal, and an output terminal connected to the gate electrode; and a second regulating circuit including a charge pump having an enable control terminal and an output terminal connected to the gate electrode, wherein the charge pump is configured to be selectively turned on based on the enable control signal to regulate the output voltage of the voltage regulator.
