Voltage regulator
A voltage regulator, regulating a supply voltage and outputting a regulated voltage. The voltage regulator comprises a two stage OP which outputs a first voltage and a second voltage according to a reference voltage and a feedback voltage. A NMOS transistor controlled by a voltage detection unit, to receive the second voltage when the detected supply voltage is in a high mode. A PMOS transistor controlled by the voltage detection unit, to receive the first voltage when the detected supply voltage is in a low mode. A feedback circuit for receiving the regulated voltage and outputting the feedback voltage to the two stage OP.
