GENERAL DESCRIPTION

The ADP3334 is a member of the ADP333x family of precision low dropout anyCAP voltage regulators. The ADP3334 operates with an input voltage range of 2.6 V to 11 V and delivers a continuous load current up to 500 mA. The novel anyCAP architecture requires only a very small 1 μF output capacitor for stability, and the LDO is insensitive to the capacitor’s equivalent series resistance (ESR). This makes the ADP3334 stable with any capacitor, including ceramic (MLCC) types for space restricted applications.

ADP3334屬于集成電路（IC） > 線性 + 開關穩(wěn)壓器。亞德諾半導體技術(shù)有限公司制造生產(chǎn)的ADP3334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)應用而言，雖然這種穩(wěn)壓器的效率低于開關模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應用。
