LM723C集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

LM723C屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由意法半導(dǎo)體集團制造生產(chǎn)的LM723C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。

DESCRIPTION

The LM723 is a monolithic integrated programmable voltage regulator, assembled in 14-lead dual in-line plastic and SO-14 micro package. The circuit provides internal current limiting. When the output current exceeds 150mA an external NPN or PNP pass element may be used. Provisions are made for adjustable current limiting and remote shut-down.

■ INPUT VOLTAGE UP TO 40V

■ OUTPUT VOLTAGE ADJUSTABLE FROM 2 TO 37V

■ POSITIVE OR NEGATIVE SUPPLY OPERATION

■ SERIES, SHUNT, SWITCHING OR FLOATING OPERATION

■ OUTPUT CURRENT TO 150mA WITHOUT EXTERNAL PASS TRANSISTOR

■ ADJUSTABLE CURRENT LIMITING
