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?
This 3-pin SMD package is difficult to hand-solder due to tight pin spacing and thermal requirements typical of power switching applications. A breakout board breaks out each pin to standard headers, enabling reliable breadboard prototyping and reducing cold-joint risk during development without needing a reflow oven or hot air station.
