1. 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
Regulates a bi-directional power with driving and sinking capability Provides achieve peak 2.0 Amp/cont. 1.8 Amp driving and sinking current Power MOSFET integrated Low external component count Low output voltage offset Operates with +3.3V and +2.5V control power Small package Low cost and easy to use
