AMS1117 3.3V Voltage Regulator

The AMS1117-3.3 is a reliable Low Dropout (LDO) voltage regulator capable of outputting a stable 3.3V from input sources up to 12V (though 5V is recommended for heat management). It can handle up to 1A of output current, making it the standard choice for powering 3.3V logic microcontrollers like the ESP8266, STM32, and modern sensors. The SOT-223 package is compact yet easy to solder for surface-mount PCB designs.
