NCP584中文资料NCP584: Linear Voltage Regulator, LDO, Tri-Mode, Low Iq, 200 mA数据手册ONSEMI规格书

描述 Description

The NCP584 low dropout (LDO) linear voltage regulator is designed for portable battery powered applications which require precise output voltage accuracy, low supply current and high ripple rejection. These devices feature an enable function which lowers current consumption significantly and are offered in the SOT23-5 package. The NCP584 Series has three modes, Chip Enable (CE mode), Fast Transient Mode (FT mode) and the Low Power Mode (LP mode). Both the FT and the LP modes are controlled via the ECO pin.

特性 Features

Low Dropout Voltage of 300 mV at 200 mA, Output Voltage = 1.0 V; 200 mV at 200 mA, Output Voltage = 1.5 V; 140 mV at 200 mA, Output Voltage = 3.0 V.
Excellent Line and Load Regulation
High Output Voltage Accuracy of 2% (3% in LP mode)
Excellent Power Supply Rejection Ratio
Low Temperature Drift Coefficient on the Output Voltage

简介

NCP584属于集成电路（IC）的稳压器-线性。由制造生产的NCP584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。
