L7818CT集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

L7818CT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(tuán)制造生產(chǎn)的L7818CT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 L7800 series of three-terminal positive

regulators is available in TO-220, TO-220FP, TO-3

and D2PAK packages and several fixed output

voltages, making it useful in a wide range of

applications. These regulators can provide local

on-card regulation, eliminating the distribution

problems associated with single point regulation.

Each type employs internal current limiting,

thermal shut-down and safe area protection,

making it essentially indestructible. If adequate

heat sinking is provided, they can deliver over 1A

output current. Although designed
