Analog Devices Inc. ADP165 超低静态电流 LDO 调节器
亚德诺半导体 ADP165 超低静态电流 LDO 调节器是一款低压差线性调节器，在 2.2V 到 5.5V 的电压范围内运行，输出电流可达 150mA 。ADP165 在 150 mA 负载下压差仅为 120 mV，可提高效率，并使器件在很宽的输入电压范围内工作。ADP165 还包括一个开关电阻，当 LDO 被禁用时，该电阻自动使输出放电。器件的短路和热过载保护电路可以防止器件在不利条件下受损。ADP165 经专门设计，通过 1µF±30% 小陶瓷输入和输出电容实现稳定工作，满足高性能、空间受限应用的要求。亚德诺半导体 ADP165 采用 WLCSP-4 封装，占位尺寸小，适用于一系列便携式电源应用，包括 & 电池供电设备、后置直流-直流调节、便携式医疗设备、（WSN）设备等。
ADP165 is designed for stable operation with a tiny 1µF ±30% ceramic input and output capacitors while meeting the requirements of high-performance, space-constrained applications.
Available in a WLCSP-4 package, the Analog Devices ADP165 offers a small footprint solution for a range of portable power applications, including portable and battery-powered equipment, post-DC-to-DC regulation, portable medical devices, and wireless sensor network (WSN) devices.
