NCP605屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由安森美半導(dǎo)體公司制造生產(chǎn)的NCP605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。

The NCP605/NCP606 provide in excess of 500 mA of output

current at fixed voltage options or an adjustable output voltage from

5.0 V down to 1.25 V. These devices are designed for space

constrained and portable battery powered applications and offer

additional features such as high PSRR, low noise operation, short

circuit and thermal protection. The devices are designed to be used

with low cost ceramic capacitors and are packaged in the DFN6 3x3.3.

NCP605 is designed without enable pin, NCP606 is designed with

enable pin.
