Abstract:
Disclosed is a voltage regulator. The voltage regulator includes a reference voltage circuit, a noise cancellation circuit, an error amplifier, a pass transistor and a voltage divider. The voltage regulator can cancel the noise generated by the reference voltage circuit and the error amplifier, and also can improve its Power Supply Rejection Ratio (PSRR).
