Product Description

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.

The CM3106 provides over current and over tempera ture protection which protects the device from excessive heating due to high current and high temperature. A shutdown capability using an external transistor reduces power consumption and provides a high impedance output.

The CM3106 is housed in both 8-lead SOIC and PSOP packages and is available with optional lead-free finishing.
