Abstract: A voltage regulation circuit includes a first comparison and control unit and a second comparison and control unit. The first comparison and control unit is connected to a first switch unit, determine a first bias voltage based on a first output voltage, a first reference voltage, and a second reference voltage, and control a value of an equivalent resistance of the first switch unit using the first bias voltage. The second comparison and control unit is connected to a third switch unit and the second switch unit, determine a second bias voltage based on the first output voltage, a second output voltage, and a third reference voltage, and control values of equivalent resistances of the third switch unit and the second switch unit using the second bias voltage.
