Abstract :
A novel approach to implement low dropout (LDO) regulator for low equivalent series resistance (ESR) capacitive load is presented. The design utilizes internal Miller compensation circuit, which acts only for heavy load. The compensation circuit improves frequency response of the LDO without using zero generated by the ESR of the load capacitor or feedback network. The proposed circuit was fabricated and tested in 0.6mum CMOS process technology
