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 continu-
ous 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 pro-
vide 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 ar-
eas 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 ac-
tive. A power saving advantage can be obtained in this
mode through lowering the quiescent current to180µA
@ 2.5V.
