TC2015集成電路（IC）的線性+開關穩(wěn)壓器規(guī)格書PDF中文資料

TC2015屬于集成電路（IC）的線性+開關穩(wěn)壓器。由微芯科技股份有限公司制造生產的TC2015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換為熱量。對于大多數應用而言，雖然這種穩(wěn)壓器的效率低于開關模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應用。

General Description
