W83310DS/DG
PRELIMINARY
1. General Description
The W83310DS/DG is a linear regulator provides a power achieves continuous
2.0Amp bi-directional sinking and driving capability for a high speed bus terminator
application. The chip simply implements a stable power supply which tracks half of
input power dynamically for bus terminator with a single chip; it’s also can be fixed
with the input of VREF1 and VREF2 pins following with setting of pin BOOT_SEL. The
W83310DS/DG is promoted with small footprint 8-SOP 150mil power package. With
W83310DS/DG design, a high integration, high performance, and cost-effective
solution is promoted.
