Abstract:
A regulator includes a first operational amplifier configured to receive a reference voltage and a feedback voltage and to output a node voltage based on a difference of the feedback voltage and the reference voltage; a first switch unit configured to receive the node voltage and to supply a recover current based on the node voltage; an output unit configured to output an output voltage and the feedback voltage according to a supply of the recover current; a comparison unit configured to receive the reference voltage and a feedback voltage and to sense a voltage drop of the output voltage; and a second switch unit configured to discharge the first switch unit according to the difference of the reference voltage and the feedback voltage.
