CAT6221集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

CAT6221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CAT6221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 300 mA CMOS Dual LDO CAT6221 combines in a single TSOT?23 6?lead package two low dropout regulators (LDO), each with its own enable pin.

The regulator outputs drive loads up to 300 mA. By design, the dual LDO provides fast response time during load current and line voltage changes.
