SIP21108集成電路（IC）的線性+開關穩(wěn)壓器規(guī)格書PDF中文資料

SIP21108屬于集成電路（IC）的線性+開關穩(wěn)壓器。由威世科技半導體制造生產(chǎn)的SIP21108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。

DESCRIPTION

The SiP21106 BiCMOS 150 mA low noise LDO voltage regulators are the perfect choice for low battery operated low powered applications. An ultra low ground current and low dropout voltage of 135 mV at 150 mA load helps to extend battery life for portable electronics. Systems requiring a quiet voltage source, such as RF applications, will benefit from the SiP21106 low output noise.
