描述 Description

The NCV4299A is a 150 mA precision micropower voltage regulator available with output voltages of 5.0 V or 3.3 V. It is available in an 14?lead SOIC (fused) and TSSOP-14 EPAD packages.The output voltage is accurate within ±2% with a maximum dropout voltage of 0.5 V at 100 mA for the 5.0 V version.The NCV4299A features low quiescent current of only 65 μA with a 100 μA load.The device features an adjustable reset output and an adjustable system monitor to provide shutdown early warning.The devices includes an inhibit function to turn the device off while consuming less than 1.0 μA of quiescent current.

簡(jiǎn)介

NCV4299AD屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由制造生產(chǎn)的NCV4299AD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(wú)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。
