Design a Custom BoardAbout This Component
Fixed low-dropout voltage regulator delivering 800 mA at 3.3 V output with 1 V typical dropout voltage. Features ±1% output accuracy at 25°C, internal current and thermal limiting, and 75 dB supply voltage rejection. Suitable for battery-powered and low-voltage applications requiring compact thermal performance.
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.
