G2992B

Global Mixed-mode Technology

2A DDR Bus Termination Regulator

Features

General Description

V_CNTLSupply Voltage: 3V to 5.5V

Termination Supply Voltage: 1.2V to 3.6V

The G2992B 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/ III -SDRAM. It contains a high-speed operational

amplifier that provides excellent response to the load

transients. This device can deliver 2A continuous cur-

rent in the application such as required for DDR I/ II/ III

SDRAM termination. The G2992B can easily provide

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

TT TT

DDR III(0.75V_TT) Requirements

Requires Only 20µF Ceramic Output Capacitor

Low Output Offset

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 applica-

tions. The G2992B also has a shutdown function by

SOT-23-5, SOP-8 and MSOP-8 (FD) Package

setting V

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 pro-

viding a high impendence. A power saving advantage

can be obtained in this mode through lowering the qui-
