CM3196  
2A Sink/Source DDR-I, -II Bus Termination Regulator  
Product Description  
Features  
Ideal for DDR-I, -II V applications  
The CM3196 is a sinking and sourcing regulator specif-

ically designed for DDR-I, -II V bus termination. The

can source and sink current up to 2A with a load regu-  
lation of 0.5%. This current adequately serves both sin-  
gle and dual channel DDR-I memory systems. For  
power conscious notebook applications, the CM3196

The CM3196 provides overcurrent and over tempera-  
ture protection. These features protect the chip from  
excessive heating due to high current and high temper-  
ature.  
The CM3196 is housed in an 8-pin SOIC or PSOP  
package and is available with optional lead-free finish-
