Winbond Electronics Corporation W83310DS

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.
