GENERAL DESCRIPTION The W83310S-R2 is a linear regulator which provides achieves peak 2.0 Amp/cont. 1.8 Amp bidirectional 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 W83310S-R2 is promoted with small footprint 8-SOP 150mil package. With W83301S-R2 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 peak 2.0 Amp/cont. 1.8 Amp 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 Small package y Low cost and easy to use 3.
