G2992

3A DDR Bus Termination Regulator

Features

General Description

V_CNTLSupply Voltage: 3.3V to 5.5V

Termination Supply Voltage: 1.8V to 3.6V

Support Both DDR I(1.25V ) and DDR II (0.9

The G2992 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 I / II -SDRAM. It contains a high-speed opera-

tional amplifier that provides excellent response to the

load transients. This device can deliver 3A continuous

current in the application such as required for DDR I/ II

SDRAM termination. The G2992 can easily provide

the accurate V

voltage with two external resistors

generating reference voltage. The quiescent current is

as low as 750µA @ V = 3.3V. So the power con-

CNTL

sumption can meet the low power consumption appli-

cations. The G2992 also has a shutdown function by

smaller than 0.2V, that provides Suspend

to RAM (STR) functionality. When in the shutdown

mode, the V output (on V pin) will be tri-state

providing a high impendence. A power saving advan-

tage can be obtained in this mode through lowering
