W83310S-N Datasheet, PDF (4/12 Pages) Winbond – Bus Termination Regulator

W83310S-N/W83310G-N
1. GENERAL DESCRIPTION
The W83310S-N is a linear regulator which provides achieves 1.5Amp 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-N is promoted with small footprint 8-SOP 150mil package. With W83301S-R/N design, a
high integration, high performance, and cost-effective solution is promoted.
