  • Voltage regulator with improved voltage regulator response and reduced voltage drop
    Patent number: 8710811
    Abstract: A voltage regulator includes an output drive device configured to provide an output voltage to an output terminal; an error amplifier configured to control the output drive device by taking into consideration a feedback signal from the output voltage; a first compensation unit configured to provide a first compensation signal to compensate an output signal of the error amplifier; and a second compensation unit configured to provide a second compensation signal to compensate an input signal of the error amplifier, wherein second compensation unit comprises at least two capacitors and at least one transistor configured to control the coupling of the two capacitors.
