A low dropout voltage regulator is described having a pass device,
differential amplifiers, and a feedback loop including a low pass filter.
Two differential amplifiers arranged in parallel coupled to the low pass
filter in the feedback loop provide a specified and stable DC voltage
whose input-to-output voltage difference is low. Improved stability,
reduced die area, improved power supply rejection ratio, increased
bandwidth, decreased power consumption, and better electrostatic
discharge (ESD) protection may result.
