Abstract: A voltage regulator and a control method thereof are provided to dynamically adjust an output voltage. The voltage regulator comprises a plurality of switching transistors and a control circuit. The first end of each switching transistor receives a driving voltage, and the second end of each switching transistor is electrically connected to the end which outputs the output voltage. The input end and the feedback end of the control circuit respectively receive a reference voltage and the output voltage. A plurality of output ends of the control circuit are electrically connected to the control ends of the switching transistors respectively. Switching transistors adjust the output voltage. The control circuit compares the output voltage with the reference voltage, and selectively turns the switching transistors on or off according to the comparison between the output voltage and the reference voltage, to control the output voltage to approach the reference voltage.
