LM338集成電路（IC）的穩(wěn)壓器-線(xiàn)性規(guī)格書(shū)PDF中文資料

LM338屬于集成電路（IC）的穩(wěn)壓器-線(xiàn)性。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的LM338穩(wěn)壓器 - 線(xiàn)性線(xiàn)性穩(wěn)壓器用于提供穩(wěn)定的輸出電壓，無(wú)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(kāi)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 LM138/LM238/LM338 are adjustable 3-terminal positive voltage regulators capable of supplying in excess of 5A over a 1.2V to 32V output range. They are exceptionally easy to use and require only 2 resistors to set the output voltage. Careful circuit design has resulted in outstanding load and line regulation comparable to many commercial power supplies. The LM138 family is supplied in a standard 3-lead transistor package.
