  • Low drop out voltage regulator and method therefor
    Patent number: 9553548
    Abstract: A circuit and method for regulating an output voltage are provided. The circuit includes a fully differential first stage amplifier, a second stage amplifier, and a power output driver transistor. The first stage amplifier receives a reference voltage and feedback voltage relative to an output voltage of the power output driver transistor. A differential output of the first stage amplifier is received at differential inputs of the second stage amplifier. The second stage amplifier provides a voltage at a control terminal of the power transistor. The output voltage of the power transistor is based on the voltage at the control terminal and a supply voltage coupled to the power output driver transistor.
