摘要
随着智慧城市和智能终端的飞速发展,安防监控系统得到了广泛应用,对电源管理芯片也提出了越来越高的要求。LDO(Low Dropout Linear Regulator)作为低压差线性稳压器,以低噪声、高PSRR(Power Supply Rejection Ratio)、外围简单等优点成为理想的电源管理方案,可以满足安防监控系统对与噪声非常敏感的要求。介绍了高性能LDO在安防监控中的应用,LDO的关键技术指标以及对安防监控系统的影响。
With the rapid development of smart city and smart terminal,security monitoring system is widely used,and higher requirements have been raised on power management components.LDO(low dropout linear regulator)is an ideal power management solution with low noise,high PSRR(power supply rejection ratio)and simple peripherals.It can meet the demand of security monitoring system which is very sensitive to noise.This paper introduces the application of high performance LDO in security monitoring,key technical parameters of LDO and its impact on security monitoring system.
