GENERAL DESCRIPTION www..com The W83310U is a linear regulator which provides achieves continuous 2.0 Amp 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 W83310U is promoted with TO252 power package. With W83310U design, a high integration, high performance, and cost-effective solution is promoted. 2. FEATURES Regulates a bi-directional power with driving and sinking capability Provides achieve continuous 2.0Amp driving and sinking current Power MOSFET integrated Low external component count Low output voltage offset Operates with +3.3V and +2.5V control power Power package TO252-5L Low cost and easy to use 3.
