详细说明

SPX3819 是一款正电压稳压器，具有低压差和低噪声输出。此外，该器件在 100mA 输出时，接地电流仅为 800μA。SPX3819 的初始容差最大小于 1%，并具有逻辑兼容的开关输入端。禁用该输入端后，功耗几乎降至零。其他主要特性包括反接电池保护、限流和过热关断。SPX3819 包含一个基准电压旁路引脚，可实现最佳的低噪声输出性能。凭借其极低的输出温度系数，该器件也是一款出色的低功耗电压基准。

SPX3819 非常适合用于电池供电的应用，例如无绳电话、无线电控制系统和便携式电脑。它提供多种固定输出电压选项，也提供可调输出电压选项。

该器件提供 8 引脚 NSOIC、8 引脚 DFN 和 5 引脚 SOT-23 封装。
