Patent ID: 8154265

Claim:
A low-dropout linear regulator comprises: an error amplifier including a cascaded arrangement of a differential amplifier and a gain stage, said gain stage including at least one transistor driven by said differential amplifier to produce at least one drive signal for an output stage of the regulator, wherein said at least one transistor is interposed over its source-drain line between at least one first resistive load included in a RC network creating a zero in the open loop gain of the regulator, and at least one second resistive load to produce at least one drive signal for an output stage of the regulator, wherein said at least one second resistive load is a non-linear compensation element to render current consumption linearly proportional to the load current to the regulator, and said at least one first resistive load is a non-linear element causing the frequency of said zero created by said RC network to decrease as the load current of the regulator decreases, and wherein said current consumption is made linearly proportional to the load current to the regulator without adversely affecting regulator stability.
