• Manufacturer Part Number: W83310S-R2
• Description: Bus Termination Regulator
• Manufacturer: Winbond Electronics Corp America

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.
