DDR 2/3/3L/4 memory termination voltage regulator

HTC Korea TJ2998 linear regulator is designed to meet the JEDEC SSTL specifications for termination of DDR-SDRAM.
The device contains a high-speed operational amplifier to provide excellent response to load transients. The output stage prevents shoot through while delivering up to 2A continuous current and transient peaks up to 3A with respect to PVIN operating condition in the application as required for DDR-SDRAM termination. The TJ2998 also incorporates a VTTSNS pin to provide superior load regulation and a VREF output as a reference for the chipset and DIMMs. An additional feature found on the TJ2998 is an active high enable (EN) pin that provides Suspend To RAM (STR) functionality. When EN is pulled low the VTT output will tri-state providing a high impedance output, but, VREF will remain active. A power savings advantage can be obtained in this mode through lower quiescent current

 

TJ2998 features :

  • Source and sink current
  • Low output voltage offset
  • No external resistors required
  • Linear topology
  • Suspend to RAM (STR) functionality
  • Low external component count
  • Thermal shutdown
  • Under voltage lockout and over current limit

 

TJ2998 applications :

  • DDR 2/3/3L/4 termination voltage
  • SSTL termination
  • HSTL termination
