Abstract
This invention provides a circuit including a voltage regulator and a control circuit. The voltage regulator is configured to receive an input signal to generate an output voltage. The control circuit is configured to select one of a first reference voltage and a second reference voltage as the output reference voltage based on the output signal of the voltage regulator, and to generate a control signal based on the output reference voltage to control the voltage potential of the output voltage of the voltage regulator.
