Design a Custom BoardAbout This Component
Monolithic step-down switching regulator delivering up to 3A output current at fixed 5V output. Features 150 kHz switching frequency, ±4% line/load regulation, and operates from input voltages up to 60V. Includes internal compensation, thermal shutdown, and current limiting; requires only four external components for typical 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.
