Popis: The paper presents a 0.5A fast response CMOS LDO built in a double-metal 0.5µm 5.5V CMOS technology. It includes a symmetrical op amp configured as voltage follower, having a built-in adaptive bias behavior. The frequency compensation is cascode-Miller type. The circuit consumes 55µA without load, less than 90 µA at full load, and uses a 1V voltage reference. Output current capability is 0.5A, while dropout voltage value is typical 300mV.
