LX8586-33CV集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

LX8586-33CV屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由美高森美公司制造生產(chǎn)的LX8586-33CV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。

DESCRIPTION

The LX8586/86A series ICs are low dropout three-terminal regulators with a minimum of 6A output current. Pentium? Processor, Power PCTM, Cyrix? 6x86TM and AMD-K5TM applica tions requiring fast transient response are ideally suited for this product family. The LX8586A is guaranteed to have < 1.1V at 6A and the LX8586 < 1.3V at 6A dropout voltage, making them ideal to provide well-regulated outputs of 2.5V to 3.6V using a 5V input supply. Fixed versions are also available and specified in the Available Options table below.
