G2992

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 V_TT voltage with two external resistors generating reference voltage. The quiescent current is as low as 750A @ V_CNTL = 3.3V. So the power consumption can meet the low power consumption applications. The G2992 also has a shutdown function by setting V_REF smaller than 0.2V, that provides Suspend to RAM (STR) functionality. When in the shutdown mode, the V_TT output (on V_OUT 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 50A @ V_CNTL = 3.3V.
