G2996

www.DataSheet4U.com Global Mixed-mode Technology Inc. G2996 DDR I/II Termination Regulator Features „ „ „ „ „ „ „ „ „ „ General Description The G2996 is a linear regulator designed to meet the JEDEC SSTL-18 ,SSTL-2 and SSTL-3 (Series Stub Termination Logic) specifications for termination of DDR-SDRAM. It contains a high-speed operational amplifier that provides excellent response to the load transients. This device can deliver 1.5A/0.9A continuous current and transient peaks up to 3A/1.8A in the application as required for DDRI/II-SDRAM termination. With an independent VSENSE pin, the G2996 can provide superior load regulation. The G2996 provides a VREF output as the reference for the applications of the chipset and DIMMs. The G2996 can easily provide the accurate VTT and VREF voltages without external resistors that PCB areas can be reduced. The quiescent current is as low as 280µA @ 2.5V. So the power consumption can meet the low power consumption applications. The G2996 also has an active low shutdown ( SD ) pin that provides Suspend to RAM (STR) functionality. When SD is pulled low, the VTT output will be tri-state providing a high impendence, but VREF will remain active. A power saving advantage can be obtained in this mode through lowering the quiescent current to180µA @ 2.5V. Operation Supply Voltage: 1.6V to 5.5V Low Supply Current: 280µA @ 2.5V Low Output Offset Source and Sink Current Low External Component Count No Inductor Required No external Resistors Requi...
