Abstract:
Various embodiments of the present invention provide apparatuses and methods for regulating an output voltage. For example, an apparatus is discussed that includes a low dropout regulator having a pass transistor and an amplifier and being operable to regulate the output voltage based on a feedback signal and a feedforward signal. The apparatus also includes an auxiliary low dropout regulator having an auxiliary pass transistor and an auxiliary amplifier. The auxiliary dropout regulator is operable to generate the feedforward signal and is substantially matched with the amplifier.
