• Manufacturer Part Number: w83310u
• Description: Winbond Bus Termination Regulator
• Manufacturer: Winbond Electronics Corp America

1. GENERAL DESCRIPTION
The W83310U is a linear regulator which provides achieves continuous 2.0 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
W83310U is promoted with TO252 power package. With W83310U design, a high integration, high
performance, and cost-effective solution is promoted.
