意法半导体的低压降(LDO)稳压器具有以下特点:低压降、低静态电流、快速瞬态响应、低噪声和出色的纹波抑制。

尤其是,超低压降(ULDO)稳压器是电池供电消费类应用以及便携式卫生保健器件的理想之选,因为:
  • 超低静态电流(低至1 µA)延长了电视使用寿命
  • 包括0.69 x 0.69 mm CSP在内的微型封装选项实现了最小的占位面积
由于具有高PSSR(电源抑制比)和低噪声的特点,所以可以沿着信号路径在很宽的输入电压和输出电流范围内保持高信号保真度。
 

LD39020: miniaturized low Iq, high performance LDO

The LD39020 is a miniaturized low-consumption LDO able to provide up to 200 mA current from an input voltage ranging from 1.5 to 5.5 V.
Housed in the new tiny DFN4 package  with a footprint of only 1x1mm2, LD39020 features an initial accuracy up to 0.5%, a very high power supply rejection of 80dB at 1kHz and a low quiescent current of 20 µA .
LD39020 is the ideal power supply linear regulators for the space-constrained hand-held applications, such as the last generation smartphones, tablets and portable entertainment devices.
It is available in many different options covering a range of output voltages from 0.8 V to 5 V in 50 mV steps. 

Ultra-tiny low-dropout regulator in breakthrough bumpless chip-scale package

The LDBL20 is a powerful 200 mA LDO in a tiny 0.47 x 0.47 mm innovative ST STAMP™ chip-scale package. The input voltage can range from 1.5 to 5.5 V, with 200 mV typical dropout. Rejection (PSRR) of 80 dB at 100 Hz and 50 dB at 100 kHz simplifies filtering over a wide frequency range to provide a stable rail for low-power circuitry in battery-operated applications. Quiescent current of 20 µA no-load, 100 µA full-load, and 0.3 µA in standby help maximize efficiency under all operating conditions.
