Abstract
The invention relates to a voltage regulator connected between first and second voltage references and having an output terminal for delivering a regulated output voltage. The voltage regulator includes at least one voltage divider, connected between the output terminal and the second voltage reference, and a serial output element connected between the output terminal and the first voltage reference. The voltage divider is connected to the serial output element by a first conduction path which includes at least one error amplifier whose output is connected to at least one driver for turning off the serial output element. The voltage regulator includes, between the voltage divider and the serial output element, at least a second conduction path for turning off the serial output element according to a value of the regulated output voltage in advance of the action of the first conduction path.
