CM3109 - 2A Sink/Source Regulator

General Description

The CM3109 is a sinking and sourcing regulator specifically designed for series-parallel bus termination for high speed chip set buses as well as DDR memory systems.

It can source and sink current up to 2A with high accuracy of 0.5 %.

The VTT output voltage is selectable by VDDQSEL and FSBSEL pins.

Key Features

  • Ideal for both PC Front Side Bus and DDR memory VTT.
