Product Summary
The g2996f1uf 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-SDRAM. The g2996f1uf contains a high-speed operational amplifier that provides excellent response to the load transients. The g2996f1uf can deliver 1.5A/0.9A continuous current and transient peaks up to 3A/1.8A in the application as required for DDRI/II-SDRAM termination. With an independent VSENSE pin, the g2996f1uf can provide superior load regulation. The g2996f1uf provides a VREF output as the reference for the applications of the chipset and DIMMs. Applications are (1)DDR-SDRAM termination voltage; (2)DDR-I / DDR-II termination voltage; (3)SSTL-2; (4)SSTL-3.
