Global Mixed-mode Technology

DDR Termination Regulator

Features

General Description

VIN Input Voltage Range: 2.5V to 5.5V

The G2985 is a linear regulator designed to meet the

JEDEC SSTL (Series Stub Termination Logic) speci-

fications in DDRI/II/III/IIIL/IV –SDRAM systems. It is

designed for the system which has low input voltage,

low cost, low noise and space consideration.

VLDOIN Voltage Range: 1.1V to 3.5V

Support DDR I (1.25 VTT), DDR II (0.9 VTT),

DDR III (0.75 VTT), DDR IIIL (0.675VTT) and

DDR IV (0.6 V^TT) Requirements

Stable with Output Ceramic Capacitor

PGOOD to Monitor Output Regulation

EN Input for Shutdown Function (S3 Mode)

Remote Sensing (VOSNS)

The G2985 provides accurate and fast response with

up to 2A source/sink ability in load transient to track

reference voltage with typically 20µF output capacitor.

The terminated voltage can be generated by two ex-

ternal resistors or programmed by forcing REFIN pin

at a desired voltage. Also the G2985 provides an

open-drain PGOOD flag which monitors the output

regulation and an EN signal to discharge VTT during

STR (S3) mode.
