Design a Custom BoardAbout This Component
Adjustable positive linear regulator rated for 800mA output current in an 8-pin SO PowerPad package. Features on-chip trimming for output voltage adjustment and thermal shutdown protection. Suitable for battery-powered equipment, portable electronics, and general-purpose power supply applications requiring adjustable regulated voltage outputs.
Package: SOIC-8-1EP (3.9×4.9mm, EP) · 8 pins
Why does this need a breakout?
8-pin SOIC with exposed pad is difficult to hand-solder reliably due to tight 1.27mm pitch and thermal management requirements. A breakout board brings pins to standard 0.1" spacing for breadboard prototyping while providing proper pad routing and thermal dissipation for audio amplifiers and gate drivers.
