Abstract

A linear regulator having an output stage including first and second P-channel MOS transistors series connected between a first D.C. supply terminal and an output terminal providing a regulated output voltage, and a circuit for controlling the first and second transistors capable of providing the first and second transistors with first and second control signals according to the output voltage and to the voltage at the midpoint of the series connection.
