Abstract
A voltage regulator includes a plurality of output stages and a controller. The plurality of output stages are arranged for selectively enabling to generate output voltages and output currents or not according to a plurality of control signals, respectively. The controller is arranged for sensing the output currents of the output stages, and generating the control signals according to the sensed output currents. When the controller generates the control signals to reduce a quantity of the enabled output stages, the controller determines whether a summation of the sensed output currents is greater than a first threshold or not to determine whether to enable more output stages, then a period of time later, the controller selectively determines whether the summation of the sensed output currents is greater than a second threshold or not to determine whether to enable more output stages, wherein the second threshold is lower than the first threshold.
