  • Product details

    ADP151It is an ultra-low noise,Low dropout linear regulator,采用2.2 V至5.5 V电源供电,最大输出电流为200 mA。在200 mA负载下仅有140 mV的低压差,有助于提高效率,使器件能在较宽的输入电压范围内工作。

    ADP151采用新颖的电路拓扑结构,实现了超低噪声性能,而无需旁路电容,非常适合对噪声敏感的模拟和RF应用。ADP151在提供超低噪声性能的同时,并不影响其电源抑制(PSRR)或线路与负载瞬态响应性能。200 mA负载时静态电流低至265 μA,因此ADP151适合电池供电的便携式设备使用。

    ADP151的EN输入引脚还内置一个下拉电阻。

    ADP151经过专门设计,在1 μF ± 30%小陶瓷输入和输出电容下便可稳定工作,适合高性能、空间受限应用的要求。

    它可提供1.1 V至3.3 V范围内的16种固定输出电压选项。

    短路和热过载保护电路可以防止器件在不利条件下受损。ADP151提供5引脚TSOT、6引脚LFCSP和4引脚、0.4 mm间距、无卤素WLCSP三种小型封装,是适合各种便携式供电应用要求的业界最小尺寸解决方案。
