描述 Description

The NCV8184 is a monolithic integrated low dropout tracking voltage regulator designed to provide an adjustable buffered output voltage that closely tracks (+/-3.0 mV) the reference input.The part can be used in automotive applications with remote sensors, or any situation where it is necessary to isolate the output of your regulator.The NCV8184 also enables the user to bestow a quick upgrade to their module when added current is needed, and the existing regulator cannot provide.The versatility of this part also enables it to be used as a high- side driver.

簡介

NCV8184屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由制造生產(chǎn)的NCV8184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。
