Design a Custom BoardAbout This Component
Fixed 5V linear voltage regulator in TO-252 package rated for 1A output current. Features thermal overload protection, short circuit protection, and safe operating area protection. Typical dropout voltage of 2V at 500mA makes it suitable for powering microcontrollers, sensors, and other 5V logic circuits from 7-25V input supplies.
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.
