Abstract

A low-dropout regulator comprises an output current branch (10) being arranged between a supply line (Vsupply) to provide a supply potential (VDD) and an output node (O) to provide a regulated output voltage (Vreg). The output current branch (10) comprises an output driver (20) to provide an output current (lout) at the output node (O). The output driver (20) has a control connection (G20) to apply a control voltage (Vc) to operate the output driver (20) with a different conductivity in dependence on the control voltage (Vc). The LDO comprises an input amplifier stage (30) to provide the control voltage (Vc) to the control connection (G20) of the output driver (20). The input amplifier stage (30) is configured to provide the control voltage (Vc) with a different slew rate in dependence on an increase or decrease of the output current (lout).
