MC33275ST-5.0T3集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

MC33275ST-5.0T3屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC33275ST-5.0T3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。

The MC33275 series are micropower low dropout voltage regulators available in a wide variety of output voltages as well as packages, SOT?223, SOP?8, DPAK, and DFN 4x4 surface mount packages. These devices feature a very low quiescent current and are capable of supplying output currents up to 300 mA. Internal current and thermal limiting protection are provided by the presence of a short circuit at the output and an internal thermal shutdown circuit.
