  • Product details

    ADP221为200 mA、双路输出Voltage regulator，集高电源抑制比(PSRR)、低噪声、低静态电流和低压差于一体，非常适合对性能和电路板空间要求严苛的无线应用。

    ADP221的低静态电流、低压差和宽输入电压范围可延长便携式设备的电池续航时间。在工作频率高达100 kHz时，这些器件能保持60 dB以上的电源抑制性能，而所需的电压裕量则很低。与LDO竞争产品相比，ADP220的噪声低得多，而且不需要噪声旁路电容。ADP221还内置一个有源下拉电阻，用来对输出负载快速放电。

    ADP221在0.8 V至3.3 V范围内提供许多输出电压组合，并提供过流和热保护，防止器件在不利条件下受损。
