GENERAL DESCRIPTION The W83310S-N is a linear regulator which provides achieves 1.5Amp 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 W83310S-N is promoted with small footprint 8-SOP 150mil package. With W83301S-R/N design, a high integration, high performance, and cost-effective solution is promoted. 2. FEATURES Regulates a bi-directional power with driving and sinking capability Provides achieve 1.5Amp driving and sinking current Power MOSFET integrated Low external component count Low output voltage offset Operates with +5V,+3.3V and +2.5V control power Small package Low cost and easy to use 3.
