1. GENERAL DESCRIPTION

The W83310S-R2 is a linear regulator which provides achieves peak 2.0 Amp/cont. 1.8 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 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
