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
is pulled low the V
TT
output will tri-state
that provides Suspend To RAM (STR) functionality. When
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.
