  • Product details

    ADP170/ADP171是一款低电压输入、低静态电流和低压差(LDO)的Linear regulator，工作电压范围为1.6V至3.6V，能够提供高达300mA的输出电流。在300mA的负载时，压差仅有55mV，改善了效率，并支持宽范围的输入电压。在空载时，静态电流低至23μA，使得ADP170/ADP171成为电池供电的便携式设备的理想选择。

    ADP170提供31个固定输出电压选择，范围为0.8 V至3.0 V。ADP171是一款输出电压可调的稳压器，通过设置一个外接分压器即可实现0.8V至3.0V范围内的任意输出电压。ADP170/ADP171的稳定性经过专门的优化，只需采用小型的1μF陶瓷输出电容。该器件特别适用于为数字处理器供电。ADP170/ADP171具有良好的瞬态性能，只占用极小的电路板空间。与一般的商用LDO相比，ADP170/ADP171可提供更好的电源抑制比(100kHz条件下高达20-40dB)，使得它们成为ADC以及混合信号处理器的理想电源选择，工程师可以使用小型的旁路电容器。此外，该系列器件具有优异的输出噪声性能，无需采用额外的旁路电容，因而进一步减少了PCB上的元器件数量。

    器件内部具有短路保护和过热保护电路，防止有害条件下的损坏。ADP170/ADP171采用5引脚的TSOT封装，外形尺寸最小，可满足各类便携式电源应用。
