ABSTRACT:
A linear type of voltage regulator, having at least one input terminal adapted to receive a supply voltage and one output terminal adapted to deliver a regulated output voltage, includes a power transistor and a driver circuit for the transistor. The driver circuit includes an operational amplifier having an input differential stage biased by a bias current which varies proportionally with the variations of the regulated output voltage at the output terminal of the regulator.
