Design a Custom BoardAbout This Component
Fixed positive voltage regulator delivering 1A output current at 12V with internal current limiting and thermal shutdown protection. Requires minimal external components and operates with input voltages from 5-40V. Suitable for on-card regulation and local power supply applications requiring stable 12V output.
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.
