Abstract

A voltage regulator circuit (200) has a first amplifier stage (210) with input and output terminals, a feedback terminal, a pole-inducing transistor, and a compensating network coupled to the output terminal. A second amplifier stage (220) has an input coupled to the first amplifier output, first and second current mirrors, and a pass transistor.
