3.0-5.5V 1.0A 1ch LDO_BD3541NUV

BD354XNUV是用于能够实现从超低电压输入到超低电压输出的芯片组的线性稳压器。通过使用内置的N-MOSFET功率晶体管,能够最大在导通电阻(RON =200mΩ(BD3541NUV))发生的电压差的超低输入输出电压差下使用。通过把输入输出电压差控制在很小的限度,能够实现大电流(Iomax=1.0A(BD3541NUV))输出、降低变换损耗,因此可以置换开关电源。BD354XNUV不需要开关电源必须的用于扼流圈和整流的二极管、功率晶体管,因此能够实现装置整体的成本降低和小型化。使用外置电阻能够设定0.65~2.7V的任意输出电压。另外,通过使用NRCS端子能够调整电压输出的起动时间,因此能够支持装置的电源时序。
