Design a Custom BoardAbout This Component
Fixed output positive voltage regulator delivering 500mA at 12V with ±2% output voltage tolerance. Features internal current limiting, thermal shutdown, and safe area protection for robust operation across extended temperature ranges. Commonly used for local on-card regulation in power supply circuits, eliminating distribution losses in larger systems.
Package: TO-252-2 · 3 pins
Why does this need a breakout?
This 3-pin SMD package is difficult to hand-solder due to tight pin spacing and thermal requirements typical of power switching applications. A breakout board breaks out each pin to standard headers, enabling reliable breadboard prototyping and reducing cold-joint risk during development without needing a reflow oven or hot air station.
