The CM3106 is a sinking and sourcing regulator specifically designed for providing power to DDR memory terminating resistors and companion chip set VTT power. The output voltage accurately tracks VDDQ/2. The CM3106 can source and sink current up to 2A, ideal for DDR-I memory systems, and 1.2A for DDR-II systems, while maintaining a load regulation of 0.5% in either application.
