NCV8772C集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

NCV8772C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NCV8772C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(gè)最小量，并且在工作時(shí)會(huì)將輸入端的任何多余電壓轉(zhuǎn)換為熱量。對(duì)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(duì)噪聲高度敏感的應(yīng)用。

The NCV8772C is 350 mA LDO regulator with integrated reset

function dedicated for microprocessor applications. Its robustness allows

NCV8772C to be used in severe automotive environments. Ultra low

quiescent current as low as 18 A typical makes it suitable for

applications permanently connected to battery requiring ultra low

quiescent current with or without load. This feature is especially critical

when modules remain in active mode when ignition is off. The Enable

function can be used for further decrease of quiescent current in

shutdown mode to 1 A. The NCV8772C contains protection functions

as current limit, thermal shutdown and reverse output current protection.
