NCP59800中文资料CMOS Linear Voltage Regulator with Enable, 1 A数据手册ONSEMI规格书

描述 Description

The NCP59800 is a family of 1 A low−dropout linear regulators
(LDOs) offering high power−supply ripple rejection (PSRR) and
ultra−low output noise. This series of LDOs uses an advanced
BiCMOS process to achieve very good electrical performance. It is an
ideal choice for noise sensitive Analog RF Front−Ends used in
Telecom Equipment. The NCP59800 is available in the 3 mm x 3 mm
DFN8 package.

简介

NCP59800属于集成电路（IC）的线性+开关稳压器。由制造生产的NCP59800稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。
