FEATURES  
DESCRIPTION  
The LP2995 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 LP2995 also incorporates a VSENSE  
pin to provide superior load regulation and a VREF  
output as a reference for the chipset and DDR  
DIMMS.

Low Output Voltage Offset  
Works with +5v, +3.3v and 2.5v Rails  
Source and Sink Current  
Low External Component Count  
No External Resistors Required  
Linear Topology  
Available in SOIC-8, SO PowerPAD-8 or  
WQFN-16 Packages
