NCP134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

NCP134 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
NCP134 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

• Ultra-Low Dropout of Typ. 140mV
• Allows to save power and operates with very low Vin-Vout voltage.
• Fixed Output Voltage options from 0.8V to 2.1V
• Excellent choice for low voltage Vcore applications
• 140 mV typical dropout at the full 500 mA load.
• minimizes the power loss across the regulator
• Guaranteed Output Current from 0mA to 500mA
• Very good choice for high current applications
• 0.5% Typical Output Voltage Accuracy
• Perfect fit for POL applications
• Output Current in Excess of 500mA
• Output Active Discharge option available

应用 Application

• Battery - powered and Portable Equipment
• Smartphones, Tablets
• Cameras, DVRs, Camcorders

简介

NCP134属于集成电路（IC）的ACDC转换器离线开关。由制造生产的NCP134AC DC 转换器，离线开关该系列是元器件级控制产品，用于构建将交流市电转换为直流电（通常电压大幅降低）的设备。集成和未集成系统主要开关元件的器件均包括在内。由于高输入输出电压比，以及此类系统中通常需要隔离，这些器件通常与外部变压器配合使用。尽管通常使用定制变压器来实现此用途，但也有许多专门用于此用途的库存产品，请参见“开关转换器，SMPS 变压器”标题。
