Abstract

A linear regulator with a pass device having a first terminal, a second terminal and a drive terminal is presented. The first terminal of the pass device is coupled with the supply voltage of the linear regulator. The second terminal of the pass device is coupled with the output of the linear regulator. A driver stage is coupled with the supply voltage of the linear regulator, and the drive terminal of the pass device drives the pass device with a driving voltage. A compensating circuit compensates for a change in a voltage difference between the drive terminal of the pass device and the supply voltage of the linear regulator.
