1. A voltage regulator, adapted to dynamically adjust an output voltage from a first output end of the voltage regulator, and comprising:
a plurality of switching transistors, wherein each of the plurality of switching transistor has a first end, a second end, and a control end, the first ends receive a driving voltage, the second ends are electrically connected with the first output end, and the switching transistor is configured to adjust the output voltage; and a control circuit, comprising an input end, a feedback end, a plurality of second output ends and a plurality of driving modules; wherein the input end receives a reference voltage, the feedback end receives the output voltage, the second output ends are electrically connected with the control ends of the switching transistors respectively, the plurality of driving modules are electrically connected with each other, each of the plurality of driving modules receives the reference voltage and the output voltage and electrically connects with one of the plurality of switching transistors, and the control circuit is configured to compare the output voltage with the reference voltage, and selectively turn on or off the plurality of switching transistors according to the comparison between the output voltage and the reference voltage so that the output voltage approaches the reference voltage; wherein when the output voltage approaches the reference voltage and one of the plurality of switching transistors is repeatedly switched between on and off, the voltage regulator keeps the switching transistor, which is repeatedly switched between on and off, turned on, to stabilize the output voltage; and wherein an Ith stage driving module in the plurality of driving modules selectively turns on or off the switching transistors corresponding to the Ith stage driving module according to the comparison between the reference voltage and the output voltage when receiving a triggering signal, and I is a positive integer. |
