LM9036MX-3.3/NOPB屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由美國德州儀器公司制造生產(chǎn)的LM9036MX-3.3/NOPB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 LM9036 ultra-low quiescent current regulator

features low dropout voltage and low current in the

standby mode. With less than 25μA Ground Pin

current at a 0.1mA load, the LM9036 is ideally suited

for automotive and other battery operated systems.

The LM9036 retains all of the features that are

common to low dropout regulators including a low

dropout PNP pass device, short circuit protection,

reverse battery protection, and thermal shutdown.

The LM9036 has a 40V maximum operating voltage

limit, a ?40°C to +125°C operating temperature

range, and ±5% output voltage tolerance over the

entire output current, input voltage, and temperature

range.
