LDO 稳压器,200 mA,超低泄漏,超高 PSRR,超低噪音

Favorite

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,需要非常洁净的电源。NCP700B 是一款 200 mA 低漏 (LDO) 线性稳压器,为工程人员提供了非常稳定准确的电压,且噪音超低,带有较高的电源抑制比 (PSRR),因此适用于射频应用。为了优化电池供电便携式应用的性能,NCP700B 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提供小占位,NCP700B 可以稳定使用小尺寸、低价值的电容,并采用非常小的 1.5x1.5mm WDFN6 和 TSOP-5 封装。
