MCP1725集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

MCP1725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MCP1725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(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。

Description

The MCP1725 is a 500 mA Low Dropout (LDO) linear regulator that provides high current and low output voltages in a very small package. The MCP1725 comes in a fixed (or adjustable) output voltage version, with an output voltage range of 0.8V to 5.0V. The 500 mA output current capability, combined with the low output voltage capability, make the MCP1725 a good choice for new sub-1.8V output voltage LDO applications that have high current demands.
