DESCRIPSION
The TJ2996 linear regulator is designed to meet the JEDEC SSTL-2 and SSTL-3 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 1.5A continuous
current and transient peaks up to 3A in the application as required for DDR-SDRAM termination. The
TJ2996 also incorporates a V_SENSE pin to provide superior load regulation and a V_REF output as a reference
for the chipset and DIMMs. An additional feature found on the TJ2996 is an active low shutdown ( ) pin
that provides Suspend To RAM (STR) functionality. When is pulled low the V_TT output will tri-state
providing a high impedance output, but, V_REF will remain active. A power savings advantage can be obtained
in this mode through lower quiescent current.
