SC2595
SC2595 is Integrated Linear DDR Termination Regulator manufactured by SEMTECH.
Description
The SC2595 is an integrated linear DDR termination device, which provides a plete solution for DDR termination designs; while meeting the JEDEC requirements of SSTL-2 specifications for DDR-SDRAM termination. The SC2595 can source and sink 1.5A current at the output VTT while maintaining excellent load regulation.

Features
Regulates while sourcing or sinking 1.5A AVCC range is from 2.5V to 5V Reference output Minimum number of external ponents Accurate internal voltage divider SOIC-8L EDP package. Also available in Lead-free package, fully WEEE and Ro HS pliant
Applications
DDR memory termination High speed data line termination PC motherboards Graphics boards Disk drives CD-ROM drives
VTT is designed to track the VREF voltage with a tight tolerance over the entire current range while preventing shoot through on the output stage. A VSENSE pin is incorporated to provide excellent load regulation, along with a buffered reference voltage. The SC2595 incorporates a disable function built into the AVCC pin to tri-state the output during Suspend To Ram (STR) states. (Multiple patents pending.)
