NCP59763数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The NCP59763 is a 3 A capable, low noise (4.3 μVRMS), ultra low dropout (70 mV max. at 3 A), fast load transient response linearregulator (LDO) equipped with an NMOS pass transistor without the need of external bias voltage. The device output voltage is adjustable from 0.5 V to 2.0 V through the use of an external resistor divider and also available in fixed output versions.The combination of high output current capability, ultra high PSRR across a wide frequency range and low noise makes this LDO ideal for powering noise sensitive high speed communication devices. Power sequencing application flexibility through enable pin, a user programmable soft−start and a user programmable delayed power good circuit. Very low dropout voltage (70 mV) and high output voltage accuracy (1%) enables low input voltage and higher power efficiency.These set of features makes NCP59763 LDO an ideal solution for powering analog, digital and mixed signal high current demanding circuits like analog−to−digital converters (ADCs), digital−to−analog converters (DACs), high performance serializers and deserializers (SerDes), application specific integrated circuits (ASICs), field programmable gate arrays (FPGAs), digital signal processors (DSPs).

简介

NCP59763属于集成电路（IC）的线性+开关稳压器。由制造生产的NCP59763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。
