ABSTRACT:
A low drop-out voltage regulator is compensated by providing a compensation capacitor across an output terminal of the regulator and an output lead of an input stage which compares a reference voltage and a voltage derived from a regulated output signal at the output terminal. The output from the input stage is inverted without gain before being provided to an output stage. This inversion allows Miller compensation with the compensation capacitor.
