Design a Custom BoardAbout This Component
Linear regulator designed for DDR memory bus termination voltage generation (VTT). Actively sinks and sources up to 1.8A while maintaining output voltage within 20mV accuracy. Features integrated power MOSFETs, high-speed differential amplifier for fast transient response, and thermal shutdown protection. Ideal for desktop PCs, notebooks, graphics cards, and embedded DDR memory systems.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
