MIC5233-3.3YS集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

MIC5233-3.3YS屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由微芯科技股份有限公司制造生產(chǎn)的MIC5233-3.3YS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)會將輸入端的任何多余電壓轉(zhuǎn)換為熱量。對于大多數(shù)應(yīng)用而言，雖然這種穩(wěn)壓器的效率低于開關(guān)模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應(yīng)用。

General Description

The MIC5233 is a 100 mA, highly accurate, low dropout regulator with high input voltage and ultra-low ground current. This combination of high voltage and low ground current makes the MIC5233 ideal for multicell Li-Ion battery systems.

A μCap LDO design, the MIC5233 is stable with either ceramic or tantalum output capacitors. It only requires a 2.2 μF output capacitor for stability.

Features of the MIC5233 include enable input, thermal shutdown, current limit and reverse battery protection, and reverse leakage protection.

Available in fixed and adjustable output voltage versions, the MIC5233 is offered in the 5-lead SOT23 and 3-lead SOT223 packages with a junction temperature range of –40°C to +125°C.
