ADP124/ADP125均为低静态电流、低压差线性调节器,采用2.3 V至5.5 V输入电压工作,提供高达500 mA的输出电流。驱动500 mA负载时压差仅为130 mV;低压差特性不仅可提高功效,而且能使器件在较宽的输入电压范围工作。

500 mA负载时静态电流低至210 μA,因此ADP124/ADP125非常适合电池供电的便携式设备使用。ADP124可提供1.75 V至3.3 V范围内的31种固定输出电压。ADP125是ADP124的可调版本,可通过外部分压器在0.8 V至5.0 V范围内设置输出电压。ADP124/ADP125经过专门设计,利用1 μF小陶瓷输入和输出电容便可稳定工作,适合高性能、空间受限应用的要求。

ADP124/ADP125具有内部软启动功能,启动时间恒定为350 μs。短路保护和热过载保护电路可以防止器件在不利条件下受损。ADP124/ADP125采用8引脚裸露焊盘MSOP封装。与标准MSOP封装相比,裸露焊盘MSOP封装热阻(θJA)更低。凭借低热阻封装,ADP124/ADP125可以满足多种便携式应用的需求,同时还能较大幅度地限制结温升高。

应用
  • 数码相机和音频设备
  • 便携式电池供电设备
  • 自动抄表(AMR)仪表
  • GPS和定位管理单元
  • 医疗仪器
  • 负载点电源
