MC78L18ACPRMG集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

MC78L18ACPRMG屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由安森美半導體公司制造生產(chǎn)的MC78L18ACPRMG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用。

The MC78L00A Series of positive voltage regulators are

inexpensive, easy?to?use devices suitable for a multitude of

applications that require a regulated supply of up to 100 mA. Like

their higher powered MC7800 and MC78M00 Series cousins, these

regulators feature internal current limiting and thermal shutdown

making them remarkably rugged. No external components are

required with the MC78L00 devices in many applications.

These devices offer a substantial performance advantage over the

traditional zener diode?resistor combination, as output impedance

and quiescent current are substantially reduced.
