目录产品概述 返回TOP The CXEP3474 is a linear regulator designed to meet the JEDEC SSTL (Series Stub Termination Logic) specifications in DDRI/II/III/IIIL/IV –SDRAM systems. It provides accurate and fast response with up to 1.8A source/sink ability in load transient to track reference voltage. The terminated voltage can be generated by two external resistors or programmed by forcing VREF pin at a desired voltage. Also the CXEP3474 operate in low power consumption as low as 0.7mA and it has a shutdown function by setting VREF lower than 0.15V then the VTT is turned off and discharged via an internal MOSFET. This function obtains low quiescent current as 50μA for STR mode.产品特点 返回TOP „ Support DDR I (1.25 VTT), DDR II (0.9 VTT), DDR III (0.75 VTT), DDR IIIL (0.675VTT) and DDR IV (0.6 VTT) Requirements „ VCNTL Supply Voltage: 3V to 5.5V „ Termination Supply Voltage : 1.2V to 3.6V „ Stable with Output Ceramic Capacitor „ Over Current Protection „ Thermal Shutdown Protection „ Shutdown Function for STR (S3) Mode „ Adjustable Output Voltage with Resistors „ Built-In Soft-Start „ Power MOS integrated „ SOP-8 (FD) and MSOP-8 (FD) Package „ RoHS Compliant 应用范围 返回TOP „ DDR I/II/III/IIIL/IV Memory Termination „ SSTL_3, SSTL_2, SSTL_18, SSTL_15 „ Notebook/Desktop/Server „ Telecom/Datacom, GSM Base Station, LCD-TV/PDP-TV, Copier/Printer, Set-Top Box 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！
