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.

簡(jiǎn)介

IFX1117MEV屬于集成電路（IC）的線性+開(kāi)關(guān)穩(wěn)壓器。由制造生產(chǎn)的IFX1117MEV穩(wěn)壓器 - 線性線性穩(wěn)壓器用于提供穩(wěn)定的輸出電壓，無(wú)論負(fù)載電流、輸入電壓或環(huán)境因素如何變化，這些輸出電壓通常都要保持不變。它們的工作原理要求輸入電壓維持在高于所需的輸出電壓，而且要超出某個(gè)最小量，并且在工作時(shí)會(huì)將輸入端的任何多余電壓轉(zhuǎn)換為熱量。對(duì)于大多數(shù)應(yīng)用而言，雖然這種穩(wěn)壓器的效率低于開(kāi)關(guān)模式的穩(wěn)壓器，但它們通常更適合對(duì)噪聲高度敏感的應(yīng)用。
