Design a Custom BoardAbout This Component
Positive adjustable linear regulator capable of supplying 3A continuous output current. Features internal current limiting and thermal shutdown protection. Output voltage is adjustable from 1.25V to 37V via external resistor divider. Commonly used in power supply applications requiring moderate current and voltage regulation with minimal component count.
Package: TO-263-2 · 3 pins
Why does this need a breakout?
This SMD package requires a breakout board to interface with breadboards and standard prototyping layouts. The three-pin configuration with large copper pad underneath demands reflow soldering or careful hand-soldering to avoid cold joints, making a breakout board with standard 0.1" headers essential for reliable connections. Ideal for power regulators and MOSFETs where thermal performance and ease of iteration matter.
