SGM2019-ADJ 圣邦微稳压器

SGM2019-ADJ系列低功耗、低噪声低压CMOS线性稳压器操作从2.5 v至5.5 v的输入电压。他们是完美的选择低电压,低功耗的应用程序。当前较低的地面使这部分对电池供电的电力系统的吸引力。SGM2019系列还提供超低压差在便携式电子设备延长电池寿命。系统需要一个安静的电压源,如射频应用,将受益于SGM2019系列的超低噪音(30μvrms)和高PSRR输出。外部噪声旁路电容器连接到设备的BPpin可以进一步降低噪音水平。SGM2019-ADJ系列低功耗、低噪声低压CMOS线性稳压器

输出电压是预设电压1.2 v至5.0 v的范围。其他功能包括一个10 na逻辑控制关闭模式,监听限流和热停堆保护。

SGM2019可用在绿色SOT-23-5和SC70-5包。它运行在一个环境温度-40℃+ 85℃SGM2019-ADJ系列低功耗、低噪声低压CMOS线性稳压器
