ADP3300ART-3屬于集成電路（IC）的線性+開關穩(wěn)壓器。由亞德諾半導體技術(shù)有限公司制造生產(chǎn)的ADP3300ART-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。

GENERAL DESCRIPTION

The ADP3300 is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. The ADP3300 stands out from conventional LDOs with a novel architecture and an enhanced process. Its patented design requires only a 0.47 μF output capacitor for stability. This device is stable with any capacitor, regardless of its ESR (Equivalent Series Resistance) value, including ceramic types (MLCC) for space restricted applications. The ADP3300 achieves exceptional accuracy of ±0.8 at room temperature and ±1.4 overall accuracy over temperature, line and load variations. The dropout voltage of the ADP3300 is only 80 mV (typical) at 50 mA.

The ADP3300 operates with a wide input voltage range from 3.0 V to 12 V and delivers a load current in excess of 50 mA. It features an error flag that signals when the device is about to lose regulation or when the short circuit or thermal overload protection is activated. Other features include shutdown and optional noise reduction capabilities. The ADP330x anyCAP LDO family offers a wide range of output voltages and output current levels from 50 mA to 200 mA:

ADP3301 (100 mA)

ADP3303 (200 mA)
