MC7812BT集成電路（IC）的線性+開(kāi)關(guān)穩(wěn)壓器規(guī)格書(shū)PDF中文資料

MC7812BT屬于集成電路（IC）的線性+開(kāi)關(guān)穩(wěn)壓器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC7812BT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(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。

These voltage regulators are monolithic integrated circuits designed as fixed?voltage regulators for a wide variety of applications including local, on?card regulation. These regulators employ internal current limiting, thermal shutdown, and safe?area compensation. With adequate heatsinking they can deliver output currents in excess of 1.0 A. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents.
