Patent ID: 7218084

Claim:
An integrated circuit comprising: a low dropout voltage (LDO) regulator, the LDO regulator including: an operational amplifier, wherein the amplifier includes an output stage and a power stage, wherein the output stage includes a main output and up to n auxiliary outputs, wherein the main output deliverers a main control voltage and each of the n auxiliary outputs delivers at least one of n auxiliary control voltages, where n is a positive integer; and wherein the power stage which is fed back to the operational amplifier and delivers an output current when coupled to a load, wherein the power stage has a main power transistor with a gate controlled by the main control voltage, and up to p power modules of identical layout with a number p less than or equal to a number n, and wherein each of the p power modules have an auxiliary power transistor with a gate controlled by one of the n auxiliary control voltages, where p is a positive integer.
