描述 Description

The NCP186 is a Very Low Dropout Regulator which provides up to 1 A of load current and maintains excellent output voltage accuracy of 1.0 % in -40 to 85degC range. The operating input voltage range from 1.8 V up to 5.5 V makes this device suitable for Li?ion battery powered products as well as post?regulation applications. The product is available in several fixed output voltage option and others are possible on request in range from 1.2 V to 3.9 V. NCP186 is fully protected against overheating and output short circuit.
Small 8?pin XDFN6 1.2 mm x 1.6 mm package makes the device especially suitable for space constrained applications.

簡(jiǎn)介

NCP186屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由ONSEMI制造生產(chǎn)的NCP186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。
