ADP170AUJZ-1.2-R7集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

ADP170AUJZ-1.2-R7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ADP170AUJZ-1.2-R7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 ADP170/ADP171 are low voltage input, low quiescent current, low-dropout (LDO) linear regulators that operate from 1.6 V to 3.6 V and provide up to 300 mA of output current. The low 66 mV dropout voltage at 300 mA load improves efficiency and allows operation over a wide input voltage range. The low 23 μA of quiescent current at a 0 mA load makes the ADP170/ADP171 ideal for battery-operated portable equipment.
