W83310S-R/N
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.
