A voltage regulator. A pass element has a control gate and outputs an output voltage according to an input voltage and a control signal received from the control gate. A feedback circuit generates a feedback signal according to the output voltage. A bandgap circuit generates a reference voltage according to the output voltage. An amplifier generates a first signal according to the feedback signal and the reference voltage. A start-up circuit generates the control signal according to the reference voltage and the first signal.
