Abstract

Low noise, low dropout regulators are described. An example low noise, low dropout regulator includes a chopping error amplifier to receive an input signal and a feedback signal and to output a modified signal having an undesired portion of the input signal shifted to a higher frequency and a regulator to receive the modified signal and to generate an output signal by filtering the undesired portion of the input signal from the modified signal.
