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.
