Abstract: A voltage regulation circuit, device, and method are disclosed, which relate to the field of electronic technologies, to reduce a voltage regulation time, and improve a system response and user experience. The voltage regulation circuit (1) includes: a first power supply circuit (11), configured to receive a voltage setting signal (SSET), and output a first supply voltage (V1) and a second reference voltage (VREF2) according to the voltage setting signal (SSET) and a difference between a first feedback voltage (VF1) and a second feedback voltage (VF2), where the first feedback voltage (VF1) is used to indicate the first supply voltage (V1), and the second feedback voltage (VF2) is used to indicate a second supply voltage (V2); and a second power supply circuit (12), configured to output the second supply voltage (V2) based on the second reference voltage (VREF2).
