低 Iq LDO稳压器

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)。

STLQ020, our LDO drops the mic
with fast response and 300 nA of quiescent current

STLQ020 Ultra-low consumption

STLQ020 series of 200 mA low-dropout voltage regulators has a quiescent current as low as 300 nA, without any compromise on performance. Thanks to a dedicated low power design and load-adaptive circuity, the STLQ020 offers much better dynamic behavior than other comparable LDOs on the market, such as higher PSRR (> 40 dB up to 200 kHz) and faster line/load transient response. It is the ideal companion to supply low-consumption microcontrollers, sensors and other small loads in space-constrained devices powered by coin or Li-Ion cells and working mainly in stand-by mode. The STLQ020’s tiny flip-chip-4 and DFN-6 packages can fit wellness monitors, medical sensors, and wireless IoT devices. The STLQ020 operates with an input voltage from 1.5 to 5.5 V, with a selection of output voltages from 0.8 to 4.5 V plus an adjustable version.

STLQ015 ultra-low quiescent current linear regulators

STLQ015系列超低功耗LDO具有1.5~5.5 V的输入电压范围,能够提供高达150 mA的电流。它们具有低至1.4 μA的静态电流(在最大负载下)和1 nA(典型值)的待机电流,为那些需要极长待机时间的应用延长了电池使用寿命。它们只需要2个小外部电容,提供了经济且节约空间的解决方案,能够为便携式和电池供电系统、电子传感器、家庭医疗器械和便携式娱乐产品内的微控制器供电。STLQ015系列具有输入电压范围宽(100 mV步内0.8 ~ 3.3 V)的特点。
