发明名称 LOW DROP OUT VOLTAGE REGULATOR AND RELATED METHOD OF GENERATING A REGULATED VOLTAGE
摘要 A low drop out voltage regulator includes an operational transconductance amplifier configured to be supplied with a supply voltage of the regulator, receive as inputs a reference voltage and a feedback voltage, and generate an intermediate current based upon a difference between the reference voltage and the feedback voltage. A current-to-voltage amplification stage is configured to be supplied with a boosted voltage greater than the supply voltage from a high voltage line, receive as input the intermediate current, and generate a driving voltage that is changed based upon the intermediate current. A pass transistor is controlled with the driving voltage to keep constant on a second conduction terminal thereof a regulated output voltage. A feedback network generates the feedback voltage based on the regulated output voltage.
