CXTP65160 CXTP65161 CXTP65162是一种简单、经济、高速的线性稳压器,用于在双数据率(DDR)存储系统中产生终端电压,以满足JEDEC SSTL_和SSTL_或其他特定接口(如HSTL、SCSI-2和SCSI-3等)的设备要求。该稳压器能够在将输出电压调节到40毫伏以内的同时,主动吸收或吸收高达2A的电压。输出端电压cab通过两个外部分压电阻器严格调节到跟踪1/2VDDQ,或通过外部施加REFEN pin电压来编程所需的输出电压。CXTP65162 CXTP65161 CXTP65160还集成了一个高速差分放大器,以在线路/负载瞬态中提供超快响应。其它特性包括极低的初始偏置电压、良好的负载调节、双向限流和片上热关机保护。CXTP65162 CXTP65161 CXTP65160在PSOP-8(外露衬垫)表面安装包中提供
