    Abstract

    An all-MOSFET low-power low-dropout regulator is designed in CMOS technology, featuring low sensitivity with respect to input voltage and temperature. Supply voltage can be as low as 800mV. An error amplify (EA) with an embedded voltage reference (EVR) is employed and a buffer is used to improve the load transient. The circuit is simulated in 0.18 μm CMOS technology. Simulated results verify that the proposed LDO is stable for a capacitive load from 0 to 10 pF and with load capability of 50 mA. The maximum overshoot and undershoot under a 0.8 V supply are less than 90 mV for full load current changes within 1 μs edge time, and the recovery time is less than 1.5 μs. The temperature coefficient (TC) is 37.8 ppm/°C ranging from -25 °C to 100 °C.
