1. GENERAL DESCRIPTION

The W83310S-R/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-R/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.
