NCP145中文资料LDO Regulator with Bias Rail and Very Low Dropout, 500 mA数据手册ONSEMI规格书

描述 Description

NCP145 is a 500 mA LDO equipped with NMOS pass
transistor and a separate bias supply voltage (VBIAS). The device
provides very stable, accurate output voltage with low noise suitable
for space constrained, noise sensitive applications. In order to
optimize performance for battery operated portable applications, the
NCP145 features low IQ consumption. The XDFN4 1.2 mm x 1.2 mm package is optimized for use in space constrained applications.

特性 Features

简介

NCP145属于集成电路（IC）的PMIC-稳压器-DCDC开关式控制器。由制造生产的NCP145DC-DC 开关控制器PMIC（电源管理集成电路）DC 到 DC 开关式控制器是用于高效率电路的稳压 IC，其配置为生成高于（突升或步升）或低于（突降或步降）输入电源的输出电源电压。其他拓扑结构可能包括：降压-升压、反激、正激、Cuk、SEPIC、全桥、半桥和推挽式。这些器件不同于需要最小电压并“烧尽”多余电压的线性稳压器。
