DESCRIPTION

The LX8383/8383A/8383B series ICs are positive regulators designed to provide 7.5A output current. All internal circuitry is designed to operate down to a 1V in put-to-output differential, so the LX8383/83A/83B can operate with greater efficiency than previously available devices.

LX8383屬于集成電路（IC） > 線性 + 開關(guān)穩(wěn)壓器。美高森美公司制造生產(chǎn)的LX8383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。
