GENERAL DESCRIPTION

The W83310G-R2 is a linear regulator provides power with the capability of continuous

1.8Amp bi-directional sinking and driving capability for a high speed bus terminator

application. The chip simply implements a stable power supply which tracks dynamically

half of the input power for the bus terminator. The W83310G-R2 is promoted with small

footprint 8-SOP 150mil package. The design of the W83310G-R2 provides a high

integration, high performance, and cost-effective solution.
