ADP3330ART-3.3集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

ADP3330ART-3.3屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADP3330ART-3.3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，而且要超出某個最小量，并且在工作時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 ADP3330 is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. The ADP3330 operates with an input voltage range of 2.9 V to 12 V and delivers a load current up to 200 mA. The ADP3330 stands out from the conventional LDOs with a novel architecture and an enhanced process that enables it to offer performance advantages and higher output current than its competition. Its patented design requires only a 0.47 μF output capacitor for stability. This device is insensitive to output capacitor Equivalent Series Resistance (ESR), and is stable with any good quality capacitor, including ceramic (MLCC) types for space-restricted applications.
