和电源噪声说「拜拜」！因为这颗具有超高PSRR的LDO-电子发烧友网

Digi-Key Daily短视频

选择一款电源管理器件，需要根据实际应用场景去权衡不同的参数指标。在对电源输出纹波有比较高要求的射频和无线等应用，我们就需要着重考量电源管理器件的电源抑制比（PSRR）这个参数，因为其反映出的是电路对于输入电源中纹波抑制，PSRR越高，我们就能够得到更加“干净”、稳定的电源输出。

为了适应这样的应用需求，ON Sem iconductor推出了NCV816x和 NCP16x系列线性稳压器（LDO），它们能够提供250mA至700mA输出电流，并具有低静态电流和极佳的负载/线路瞬变等特性。

当然，NCV816x 和 NCP16x最大的优势还在于超高的PSRR，其可以提供业内领先的98dBPSRR性能。NCV816x主要适用于汽车图像传感器，NCP16x则可用于噪声敏感型Wi-Fi模块，它们出色的PSRR性能可通过滤除电源噪声改善图像传感器画质，通过提供干净的电源，最大限度提高每位电源效率。

有关NCV816x和NCP16x LDO的介绍，参见以下视频：
