NCV59744MNADJTBG集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

NCV59744MNADJTBG屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由安森美半導(dǎo)體公司制造生產(chǎn)的NCV59744MNADJTBG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。

The NCV59744 is dual?rail very low dropout voltage regulator that

is capable of providing an output current in excess of 3.0 A with a

dropout voltage of 115 mV typ. at full load current. The devices are

stable with ceramic and other low ESR output capacitors. This series

contains adjustable output voltage version with output voltage down

to 0.8 V. Internal protection features consist of built?in thermal

shutdown and output current limiting protection. User?programmable

Soft?Start and Power Good pins are available. The NCV59744 is

available in QFN20?5x5?0.65P package.
