描述 Description

The TC1108 is a fixed output, high accuracy (typically ±0.5%) CMOS low dropout regulator. Total supply current is typically 50 μA at full load (20 to 60 times lower than in bipolar regulators). TC1108 key features include ultra low noise, very low dropout voltage (typically 240 mV at full load) and fast response to step changes in load. The TC1108 incorporates both over-temperature and over-current protection. The TC1108 is stable with an output capacitor of only 1μF and has a maximum output current of 300 mA. It is available in a SOT-223 package.

簡(jiǎn)介

TC1108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TC1108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。
