BD3533F
針對DDR-SDRAM的終端用線性電源

BD3533F是適用於JEDEC標準DDR-SDRAM的終端穩壓器。內建N-MOSFET,漏極/源極最大可提供1A電流的線性電源。內部的OP-AMP採用高速設計,實現了優異的暫態響應特性。為驅動內部的N-MOSFET,需要3.3V或5.0V偏壓電源。為確保JEDEC規定的電壓精度,本產品擁有獨立的基準輸入引腳(VDDQ)和獨立的反饋引腳(VTTS),實現了優異的輸出電壓精度和負載調整率。還有DDR-SDRAM、存儲器控制器用基準電源輸出引腳(VREF)。EN引腳=L時,VTT輸出為Hi-Z,並保持VREF輸出,對應DDR-SDRAM的Self Refresh狀態。
