低静态电流LDO是一种经过优化的低压降稳压器,可在超低静态电流(Iq, 或自功耗)— 低于或相当于它提供的平均负载电流 — 下运行。
该特性对于功率敏感型应用是必需的,比如需要长期待机运行的电池供电设备或符合绿色标准的设备,可延长电池寿命、降低总体功耗。
意法半导体的低静态电流LDO稳压器非常适合便携式消费设备,如智能手机、智能手表、蓝牙耳机以及可穿戴设备。工业、智能楼宇和智能家居传感器也可以受益于非常低的静止电流,无论是处于工作模式还是禁用(待机)模式。其他应用包括智能仪表、医疗设备和钮扣电池供电的设备。
提供多种小尺寸封装选项,包括SOT23-5L、SOT323-5L、Flip-Chip4(0.65 x 0.65 mm)、以及DFN(1 x 1 mm)。
