面向DDR-SDRAM的终端用线性电源_BD3533F

BD3533F是适用于JEDEC标准DDR-SDRAM的终端稳压器。内置N-MOSFET,漏型/源型最大可提供1A电流的线性电源。内部的OP-AMP采用高速设计,实现了优异的瞬态响应特性。为驱动内部的N-MOSFET,需要3.3V或5.0V偏压电源。为确保JEDEC规定的电压精度,本产品拥有独立的基准输入引脚(VDDQ)和独立的反馈引脚(VTTS),实现了优异的输出电压精度和负载调整率。还有DDR-SDRAM、存储器控制器用基准电源输出引脚(VREF)。EN引脚=L时,VTT输出为Hi-Z,并保持VREF输出,对应DDR-SDRAM的Self Refresh状态。
