General Description
The G2995 is a linear regulator designed to meet the
JEDEC SSTL-2 and SSTL-3 (Series Stub Termination
Logic) specifications for termination of DDR-SDRAM.
It contains a high-speed operational amplifier that pro-
vides excellent response to the load transients. This
device can deliver 1.5A continuous current and tran-
sient peaks up to 3A in the application as required for
DDR-SDRAM termination. With an independent VSENSE
pin, the G2995 can provide superior load regulation.
The G2995 provides a VREF output as the reference for
the applications of the chipset and DIMMs.
The G2995 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 280A @ 2.5V. So the power consumption can
meet the low power consumption applications.
