NCP171 是一款双模式 LDO，在活动模式下提供高达 80 mA 的电流，在低功耗模式下提供低至 50 nA 的 Iq。双模式功能可通过 ECO 引脚选择，允许在活动模式和低功耗模式之间动态切换，非常适合长寿命电池供电的无线应用。低功耗模式下的输出电压可以降低内部工厂编程值，范围为 50 mV、100 mV、150 mV 或 200 mV，相对于活动模式下的标称输出电压。

The NCP171 is a Dual mode LDO offering up to 80 mA in Active Mode and as low as 50 nA of Iq in Low Power Mode. The Dual Mode function is selectable with the ECO pin allowing for dynamic switching between Active and Low Power Modes, ideal in long life battery powered wireless applications. The output Voltage in Low Power mode can be lowered by an internally factory programmed value ranging 50 mV, 100 mV, 150 mV or 200 mV with respect to the nominal output voltage in Active Mode.
