An essential component of today’s battery powered SoC’s are power management systems which include Low Drop-Out (LDO) voltage regulators. LDO voltage regulators improve battery’s power efficiency and life. In this paper design and analysis of an LDO voltage regulator is presented. The designed LDO voltage regulator is designed with self-compensated error amplifier. It provides 30mA load current with a stable 1.6V output voltage. It consumes 172μA quiescent current and has a power efficiency of 88.38% with dropout voltage of 200mV. © 2015, Scientific Publishers. All rights reserved.
