Global Mixed-mode Technology Inc.

DDR Termination Regulator

General Description

G2993

Features

^ꢀOperation Supply Voltage: 1.6V to 5.5V

^ꢀLow Supply Current: 280µA @ 2.5V

^ꢀLow Output Offset

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.

^ꢀSource and Sink Current

^ꢀLow External Component Count

^ꢀNo Inductor Required

^ꢀNo external Resistors Required

^ꢀThermal Shutdown Protection

^ꢀSOP-8L package

The G2993 can easily provide the accurate V_TTvolt-

ages without external resistors that PCB areas can be

reduced. The quiescent current is as low as 280µA @

2.5V. So the power consumption can meet the low

power consumption applications.

Applications

^ꢀDDR-SDRAM Termination Voltage

^ꢀDDR-I / DDR-II Termination Voltage

^ꢀSSTL-2

^ꢀSSTL-3
