MCP1727集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

MCP1727屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由微芯科技股份有限公司制造生產(chǎn)的MCP1727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(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。

Description

The MCP1727 is a 1.5A Low Dropout (LDO) linear regulator that provides high current and low output voltages in a very small package. The MCP1727 comes in a fixed (or adjustable) output voltage version, with an output voltage range of 0.8V to 5.0V. The 1.5A output current capability, combined with the low output voltage capability, make the MCP1727 a good choice for new sub-1.8V output voltage LDO applications that have high current demands.
