Design a Custom BoardAbout This Component
Low-dropout linear voltage regulator delivering 3.3V at 5A output current in a TO-252 (DPAK) surface-mount package. Features low quiescent current and thermal shutdown protection, suitable for powering microcontrollers, FPGAs, and other 3.3V logic circuits. Commonly used in battery-powered and space-constrained applications requiring stable regulated power.
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.
