EZ1083CT集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

EZ1083CT屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由Semtech Corporation制造生產(chǎn)的EZ1083CT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 EZ1083 series of high performance positive voltage regulators are designed for use in applications requiring low dropout performance at full rated current. Additionally, the EZ1083 series provides excellent regulation over variations in line, load and temperature.

Outstanding features include low dropout performance at rated current, fast transient response, internal current limiting and thermal shutdown protection of the output device. The EZ1083 has both fixed and adjustable voltage options, while the EZ1083B is adjustable only for cost sensitive applications. These devices are available in the popular TO-220 package.
