Abstract
A voltage regulator includes an error amplification circuit, a voltage detection circuit, a loop current prevention circuit, a voltage regulation circuit, and a stable voltage output terminal; the voltage regulation circuit outputs a voltage of the second power supply to the stable voltage output terminal when receiving a first control signal and second control signal output by the voltage detection circuit and stops outputting the voltage of the second power supply when receiving a third control signal and fourth control signal output by the voltage detection circuit; the loop current prevention circuit prevents a loop from being formed between the first power supply and the stable voltage output terminal when receiving the first control signal and the second control signal and controls the error amplification circuit to output an error amplification signal to the stable voltage output terminal when receiving the third control signal and the fourth control signal.
