CM3106

2 Amp Source/ Sink Bus Termination Regulator

Product Description

Features

•

Ideal for DDR-I and DDR-II V applications

The CM3106 is a sinking and sourcing regulator specif-

ically designed for providing power to DDR memory

terminating resistors and companion chip set V

Sinks and sources 2.0A for DDR-I

Over current protection

•

Over temperature protection

Integrated power MOSFETs

Excellent accuracy (0.5% load regulation)

Pin and functionally compatible with LP2995

8-lead SOIC and PSOP packages

Lead-free versions available

power. The output voltage accurately tracks V

/2.

DDQ

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 exces-

sive heating due to high current and high temperature.

A shutdown capability using an external transistor

reduces power consumption and provides a high

impedance output.

Applications

•

Single and Dual Channel DDR Memory

Bus Termination

•

Active Termination Buses

Graphics Card Memory Termination

The CM3106 is housed in both 8-lead SOIC and PSOP

packages and is available with optional lead-free finish-

ing.
