Design a Custom BoardThe AMS1117CD-3.3 is a fixed-output 3.3V low-dropout linear regulator rated for 1A continuous current with typical 1.2V dropout at full load. It features ±1.5% output accuracy, integrated current limiting, and thermal shutdown protection. Suitable for portable electronics, battery-powered systems, and post-regulation in switching supplies.
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.
