Abstract: A voltage regulator having an output terminal provided for being connected to a load, including an amplifier having its inverting input connected to a reference voltage, and its non-inverting input connected to the output terminal, a charge capacitor arranged between the output terminal and a first supply voltage, first and second voltage-controlled switches each arranged to connect a second supply voltage and the output terminal, and a control means adapted to providing a voltage depending on the output voltage of the amplifier, on the one hand, to the gate of the first switch and, on the other hand, when the current flowing through the first switch reaches a predetermined threshold, to the gate of the second switch.
