Abstract
A voltage regulator having an output terminal adapted to being connected to a load, including an operational amplifier having its non-inverting input connected to a first reference voltage, and its inverting input connected to the output terminal, an inverting stage having its input connected to the output of the operational amplifier, a power switch controlled by the output of the inverter stage, arranged between the output terminal and a supply voltage, and a charge capacitor arranged between the output terminal and a reference supply voltage, including a means for reducing the effective output impedance of the operational amplifier.
