Design a Custom BoardAbout This Component
Fixed positive linear voltage regulator delivering 5V at up to 500mA output current in a thermally efficient DPAK package. Features ±2% output voltage tolerance, internal current limiting, thermal shutdown, and short-circuit protection for robust operation across extended temperature ranges. Ideal for on-card local voltage regulation in embedded systems, consumer electronics, and industrial applications.
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.
