描述 Description

The MCP1703 is a CMOS, low dropout voltage regulator with 250 mA maximum output current. MCP1703 works with input voltage of up to 16V and in combination with its low current consumption of 2 μA is an ideal solution for applications using multi-cell, 9V alkaline or one-, two-?or three- cell lithium-ion batteries. It is available in space efficient SOT23A and SOT89 packages or in a thermally capable 3-pin SOT223.For new designs, please consider the MCP1703A, which contains several improvements over the MCP1703.

簡(jiǎn)介

MCP1703屬于集成電路（IC）的線性+開(kāi)關(guān)穩(wěn)壓器。由制造生產(chǎn)的MCP1703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(wú)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(kāi)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。
