BD00EA5WHFP
高耐壓 500mA 可變輸出型 LDO穩壓器

BD00EA5Wxxx系列是低消耗電流線性穩壓器。該IC具有45V耐壓，500mA輸出電流，17μA消耗電流（典型值）。輸出電壓精度BD00EA5WFP和BD00EA5WFP為±1％，BD00EA5WFP2為±1.5％（不包括回饋電阻精度）。透過在ADJ引腳上增加一個電阻，可以將輸出電壓設置為1.2V至16V。有一個輸出關閉功能，當EN引腳施加High電壓時，IC輸出開啟，施加LOW電壓時輸出關閉。該IC具有過流保護功能，可防止因輸出短路等導致的IC損壞，以及過熱保護電路，可防止IC因超載等原因造成熱損壞等。輸出相位補償電容可使用低ESR陶瓷電容器。
