LDO Performance and Development Trend Study

Abstract

A low dropout linear regulator (LDO) is responsible for providing a stable supply voltage in a circuit system. Due to the characteristics of LDOs such as low power consumption, low noise, good stability, etc., it has become an essential key component of modern electronic equipment. With the continuous updating and development of electronic equipment, people have higher and higher requirements for LDOs. Therefore, the new design scheme, manufacturing process, and testing method of LDOs have become one of the hotspots in nowadays' research. To understand the current research status, development trend, and challenges of LDOs chips, this essay researches a large amount of literature, summarizes the research results of previous researchers, and explores the application prospects of LDOs in emerging technologies. The paper proposes a program that can be improved and gives an outlook on the future research direction.
