Design a Custom BoardAbout This Component
Fixed-output positive linear regulator delivering 500 mA at 5V with ±2% voltage tolerance. Features integrated thermal overload protection, short-circuit protection, and safe-area output protection. Suitable for local on-card voltage regulation in diverse applications with adequate heat sinking.
Package: TO-252-2 · 3 pins
Why does this need a breakout?
TO-252 power MOSFETs require careful hand-soldering due to the large drain tab and tight 4.56mm lead spacing, making a breakout board essential for reliable prototyping. This board converts the package to breadboard-compatible headers and standard 0.1-inch pitch, eliminating soldering risk and enabling rapid circuit iteration for power switching applications.
