SC4215J集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

SC4215J屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由Semtech Corporation制造生產(chǎn)的SC4215J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。

Description

The SC4215J is a high performance positive voltage regulator designed for use in applications requiring very low input voltage and very low dropout voltage at up to 2 amperes. It operates with a Vin as low as 1.4V, with output voltage programmable as low as 0.5V. The SC4215J features ultra low dropout, ideal for applications where Vout is very close to Vin. Additionally, the SC4215J has an enable pin to further reduce power dissipation while shut down. The SC4215J provides excellent regulation over variations in line, load and temperature.
