DESCRIPSION
The TJ2995 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
transient. This device can deliver 1.5A continuous current and transient peaks up to 3A in the application as
required for DDR-SDRAM termination. With an independent V
SENSE
pin, the TJ2995 can provide superior load
regulation. The TJ2995 provides a V
REF
output as the reference for the chipset and DDR DIMMS. The TJ2995
can easily provide the accurate V
TT
and V
REF
voltages without external resistors that PCB areas can be
reduced. The quiescent current is low to meet the low power consumption applications.
