200 mA 低噪声射频,低漏线性稳压器

添加至我的收藏

概览

对噪音敏感的射频应用,如手机和精密仪器中的功率放大器,需要非常干净的电源。NCP700 是一款 200 mA 低漏 (LDO) 线性电压稳压器,为工程人员提供了非常稳定准确的电压,具有超低噪音和极高电源抑制比 (PSRR),适合射频应用。为了优化电池供电便携式应用的性能,NCP700 采用先进的 BiCMOS 工艺,融合了双极元件的低噪音和出众的动态性能,兼具 CMOS 在满负载条件下的极低接地电流耗量。此外,为了在空间受限的应用中占据较小的占地面积,NCP700 可以稳定使用体积小、价格低的电容,并采用非常小的 DFN6 2x2.2 封装。新设计注意:推荐使用 NCP700B 来替代 NCP700。
