Design a Custom BoardAbout This Component
Positive adjustable linear voltage regulator delivering up to 1.5A output current with user-selectable output voltage from 1.2V to 37V via external resistor divider. Features excellent line and load regulation (0.1%), integrated current limiting, thermal shutdown, and SOA protection. Ideal for laboratory supplies, automotive systems, and general-purpose power applications.
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.
