NCP4588中文资料NCP4588: Linear Voltage Regulator, LDO, Output Capacitor Free, 200 mA数据手册ONSEMI规格书

描述 Description

The NCP4588 is a CMOS 200mA LDO which is stable without an output capacitor. This results in a reduction in component count, cost and board area, as well as contributing to a more robust solution in hostile environments. With quiescentcurrent 60 dB, the device is an excellenttrade off between the two features. The family is available in a variety of packages: SC-70-5 (SC88A), SOT23-5 and a small, ultra thin 1.2 x 1.2 x 0.4 mm XDFN. The device output voltage range is 1.0 to 4.2 V with voltage outputs available in 0.1 V steps - contact you local sales office with your specific output voltage requirement.

特性 Features

Low Iq: 9.5 uA (typical)
Well suited to low power or battery powered products
Good PSRR: 70dB Vo 2.2V
Good rejection of noise or ripple introduced on the input of the regulator
Low Dropout: 270 mV typical
Vin can be close to Vout meaning less power dissipated across the regulator.
Auto-discharge feature available
Pulls output low when the device is disabled ensuring quick switchoff

应用 Application

Power Supply, POL, filtering
HDD, STB, DVD playersIndustrial meters, Smart metersCameras

简介

NCP4588属于集成电路（IC）的线性+开关稳压器。由制造生产的NCP4588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。
