1. GENERAL DESCRIPTION

The W83310U is a linear regulator which provides achieves continuous 2.0 Amp bi-directional sinking

and driving capability for DDR SDRAM bus terminator application. The chip simply implement a stable

power supply which can track half of input power dynamically for bus terminator with a single chip; that

is the chip integrates two power MOSFETs. There is no any external power device needed. The

W83310U is promoted with TO252 power package. With W83310U design, a high integration, high

performance, and cost-effective solution is promoted.

2. FEATURES

y Regulates a bi-directional power with driving and sinking capability

y Provides achieve continuous 2.0Amp driving and sinking current

y Power MOSFET integrated

y Low external component count

y Low output voltage offset

y Operates with +3.3V and +2.5V control power

y Power package TO252-5L

y Low cost and easy to use

3. APPLICATIONS

y DDR and DDR II Bus Termination Regulator

y Active Termination Bus

y SSTL-2

y SSTL-3
