KD1084集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

KD1084屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由意法半導(dǎo)體集團制造生產(chǎn)的KD1084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 KD1084 is a LOW DROP Voltage Regulatorable to provide up to 5A of Output Current. Dropout is guaranteed at a maximum of 1.5V at the maximum output current, decreasing at lower loads. The KD1084 is pin to pin compatible with he older 3-terminal adjustable regulators but has better performances in term of drop and output tolerance. A 2.85V output version is suitable for SCSI-2 active termination. Unlike PNP regulators, where a part of the output current is wasted as quiescent current, the KD1084 quiescent current flows into the load, so increase efficiency. Only a 10μF minimum capacitor is need for stability.
