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_SENSEpin, the TJ2995 can provide superior load

regulation. The TJ2995 provides a V_REFoutput as the reference for the chipset and DDR DIMMS. The TJ2995

can easily provide the accurate V_TTand V_REFvoltages without external resistors that PCB areas can be

reduced. The quiescent current is low to meet the low power consumption applications.
