Design a Custom BoardAbout This Component
Three-terminal positive linear voltage regulator providing fixed 9V output at up to 500mA. Features internal current limiting, thermal shutdown, and safe area protection for robust operation. Available in compact DPAK package suitable for on-card regulation in power supply and embedded applications.
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.
