Abstract
A low-dropout voltage regulator (2) comprises: a differential amplifier portion (4) including a first amplifier input connected to a reference voltage (16), a second amplifier input, and a differential output which is determined by a difference between the reference voltage and a voltage on the second amplifier input; an output portion (10) arranged to provide a regulator output voltage (62) which is controlled by the differential output of the amplifier portion, the second amplifier input being connected to or derived from (70) the regulator output voltage; and a biasing portion (8) arranged to measure an external load current and to provide a biasing current to the differential amplifier portion which depends on the load current.
