描述 Description

The MCP1711 is a very accurate CMOS low dropout (LDO) voltage regulator that can deliver up to 150 mA of current while consuming only 0.6 μA of quiescent current (typical). The LDO output is stable without the need of capacitors due to excellent internal phase compensation. Eliminating capacitors can save space overall solution cost. However, for better transient responses, the output capacitor should be added for enhanced performance. The MCP1711 has a true current foldback feature for added protection when the load decreases beyond the MCP1711’s load rating. The package options for the MCP1711 are the 4-Lead 1x1 mm UQFN and the 5-Lead SOT-23 which makes an ideal choice for small and compact applications.

簡介

MCP1711屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由制造生產(chǎn)的MCP1711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。
