描述 Description

The CS8182 is a monolithic integrated low dropout tracking regulator designed to provide adjustable buffered output voltage that closely tracks (± 10 mV) the reference input. The output delivers up to 200 mA while being able to be configured higher, lower or equal to the reference voltage.The output has been designed to operate over a wide range (2.8 V to 45 V) while still maintaining excellent DC characteristics. The CS8182 is protected from reverse battery, short circuit and thermal runaway conditions. The device also can withstand 45 V load dump transients and 50 V reverse polarity input voltage transients. This makes it suitable for use in automotive environments. The VREF/ENABLE lead serves two purposes. It is used to provide the input voltage as a reference for the output and it also can be pulled low to place the device in sleep mode where it nominally draws less than 30 μA from the supply.

簡介

CS8182屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由制造生產(chǎn)的CS8182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。
