LDO（低压降）是一种线性稳压器，面向运行时输入-输出电压差（压降）非常低的应用。其目的是将设备上发热带来的功率散失降至最低，从而提高转换效率。
我们的LDO稳压器系列是同类器件中最佳，包括：
LDO稳压器 vs 线性稳压器
线性稳压器 是一种经济划算的方式，用于提供稳定的输出电压，其特点是设计简单且外部组件较少。但是LDO稳压器可以在输出电流小于几安培且输出电压接近输入电压的应用中实现成本与性能的最佳平衡。
LDO稳压器 vs 开关转换器
与DC-DC开关转换器相比，LDO稳压器不产生纹波，因此可以提供非常干净的电源电压。由于所需的外部无源元件数量最少，大大减少了设计工作量。

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.
