Abstract
In this paper, the development of a low drop-out voltage regulator with multiple enable controls was described. In circuit design, a lateral PNP transistor was used as a regulating transistor, and combined band-gap reference and feedback were adopted. The low drop-out voltage regulator was processed in 0.5 um BCD process technology. It has multiple enable control. The output current was 100 mA, the output voltage was 5 V, the drop-out voltage was less than 0.5 V, and the temperature coefficient was less than 40 ppm/°C.
