電(dian)(dian)源(yuan)IC種類繁多，共同特(te)點有(you)：工(gong)(gong)作(zuo)電(dian)(dian)壓(ya)低(di)：一般的(de)(de)工(gong)(gong)作(zuo)電(dian)(dian)壓(ya)為3.0～3.6V。有(you)一些工(gong)(gong)作(zuo)電(dian)(dian)壓(ya)更低(di)，如2.0、2.5、2.7V等(deng)；也(ye)有(you)一些工(gong)(gong)作(zuo)電(dian)(dian)壓(ya)為5V，還(huan)有(you)少數(shu)(shu)12V或28V的(de)(de)特(te)殊用途的(de)(de)電(dian)(dian)壓(ya)源(yuan)。工(gong)(gong)作(zuo)電(dian)(dian)流小：從幾毫安到幾安都(dou)有(you)，但(dan)由于(yu)大(da)多數(shu)(shu)嵌入式(shi)電(dian)(dian)子(zi)產品的(de)(de)工(gong)(gong)作(zuo)電(dian)(dian)流小于(yu)300mA，所以30～300mA的(de)(de)電(dian)(dian)源(yuan)IC在品種及數(shu)(shu)量上占較大(da)的(de)(de)比例。封裝(zhuang)尺(chi)寸小：近(jin)年來發展的(de)(de)便攜式(shi)產品都(dou)采用貼片(pian)式(shi)器件，電(dian)(dian)源(yuan)IC也(ye)不例外(wai)，主(zhu)要(yao)有(you)SO封裝(zhuang)、SOT-23封裝(zhuang)，μMAX封裝(zhuang)及封裝(zhuang)尺(chi)寸小的(de)(de)SC-70及比較新的(de)(de)SMD封裝(zhuang)等(deng)，使電(dian)(dian)源(yuan)占的(de)(de)空(kong)間(jian)越來越小。雙備(bei)份(fen)電(dian)(dian)源(yuan)甚至可實(shi)現網絡集(ji)中管理。拱墅區智能雙備(bei)份(fen)電(dian)(dian)源(yuan)類型(xing)
