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.
