OBSOLETE: For Information Purposes Only. Contact Analog Devices for Potential Replacement.

The LT1003 is a 5 amp version of the popular LM123 5V regulator. In addition to higher output current, it offers improved line regulation and an initial output voltage tolerance of?±2%. These tightened specifications ease design and application problems several ways: safety margin is improved, error budgets on other parts of the system are expanded, and output voltage loss due to long supply runs can be better tolerated.

The LT1003 incorporates LTC's advanced design, process and test techniques for improved quality and reliability over similar device types. Specifically, all devices are burned in by shorting the outputs, thereby forcing the regulator into its current limit and eventually, thermal limit mode. This ensures that all device protection features are working.

簡介

LT1003屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由制造生產(chǎn)的LT1003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。
