Product Description

• 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/III/IIIL -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/III/IIIL 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 VTToutput (on VOUTpin) 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.
