IFX1117MEV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 IFX1117 is a monolithic integrated fixed NPN type voltage regulator that can supply loads up to 1.0 A. The device is housed in the small surface mounted SOT223 package. The IC is equipped with additional protection against overload, short circuit and over-temperature.The IFX1117ME V33 supplies a regulated output voltage of 3.3 V (±2%). The IFX1117ME V supplies an output voltage with ±2% precision adjustable via an external voltage divider. The input voltage for the IFX1117ME V33 ranges from 4.5 V (= VQ+VDR) to 15 V for a load current of 800 mA, for the maximum load current of 1.0 A a minimum input voltage of 4.7 V is required. The drop voltage VDR ranges from 1.1 V to 1.4 V depending on the load current level.

简介

IFX1117MEV属于集成电路（IC）的线性+开关稳压器。由制造生产的IFX1117MEV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。
