G2992 DDR Bus Termination Regulator

Brand new 3A DDR Bus Termination Regulator  G2992 SOP-8

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 operational 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 VTT voltage with two external resistors generating reference voltage. The quiescent current is as low as 750µA @ VCNTL = 3.3V. So the power consumption can meet the low power consumption applications. The G2992 also has a shutdown function by setting VREF smaller than 0.2V, that provides Suspend to RAM (STR) functionality. When in the shutdown mode, the VTT output (on VOUT pin) will be tri-state providing a high impendence. A power saving advantage can be obtained in this mode through lowering the quiescent current to 50μA @ VCNTL = 3.3V.

Features:

• VCNTL Supply Voltage: 3.3V to 5.5V
• Termination Supply Voltage: 1.8V to 3.6V
