BD18KA5WF-E2集成電路（IC）的線性+開關穩(wěn)壓器規(guī)格書PDF中文資料

BD18KA5WF-E2屬于集成電路（IC）的線性+開關穩(wěn)壓器。由羅姆半導體集團制造生產的BD18KA5WF-E2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。

General Description

The BDxxKA5 series are low-saturation regulators that are available for output currents up to 500mA. The output voltage precision is ± 1. These LDO regulators are offered in several output voltages and package lineups with or without ON/OFF switches (that set the circuit current to 0μA at shutdown). This series can be used for a broad spectrum of applications ranging from TVs and car audio systems to HDDs, PCs, and DVDs. There regulators have a built-in overcurrent protection circuit that prevents the destruction of the IC, due to output short circuits and a thermal shutdown circuit.
