描述 Description

The CS8147 is a 10V/5V dual output linear regulator. The 10V ±.5% output sources 500mA and the 5V ±3% output sources 70mA. The secondary output is inherently stable and does not require an external capacitor.
The on board ENABLE function controls the regulator?s two outputs. When ENABLE is high, the regulator is placed in SLEEP mode.
Both outputs are disabled and the regulator draws only 70μA of quiescent current.
The regulator is protected against overvoltage conditions. Both outputs are protected against short circuit and thermal runaway conditions.
The CS8147 is packaged in a 5 lead TO-220 with copper tab. The copper tab can be connected to a heat sink if necessary.

簡介

CS8147屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由制造生產(chǎn)的CS8147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用。
