ADP3330ART-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 Analog Devices, Inc., precision low dropout (LDO) anyCAP? voltage regulator family of products. 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 minimum output capacitor of 0.47 μF 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.
