ABSTRACT:
A voltage providing circuit includes: a first voltage providing circuit, for generating a first voltage; a switch device, for receiving a first voltage; a second voltage providing circuit, for providing a second voltage; a control circuit, for controlling the switch device and the second voltage providing circuit, wherein in a first mode, the control circuit turns off the switch device for allowing a target device to receive the second voltage, and in a second mode, the control circuit turns on the switch device and stops the second voltage providing circuit from providing the second voltage such that the target device can receive the first voltage; and an adjusting circuit, for providing a reference voltage to the first voltage providing circuit according to the first voltage and the second voltage for changing the first voltage, thereby making the first voltage substantially equal to the second voltage.
