General Description
The G2993 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.
The G2993 can easily provide the accurate V
TT
volt-
ages without external resistors that PCB areas can be
reduced. The quiescent current is as low as 230μA @
2.5V. So the power consumption can meet the low
power consumption applications.
