Abstract
A linear type of voltage regulator, having an input terminal adapted to receive a supply voltage thereon, and an output terminal adapted to deliver a regulated output voltage, includes a power transistor and a driving circuit therefor. The driving circuit includes an operational amplifier having a differential input stage biased by a bias current which varies proportionally with the output current of the regulator.
