About this product
LM1117T-3.3 is a fixed 3.3V low-dropout linear voltage regulator in a TO-220 package, rated for up to 800mA output. It provides a stable 3.3V supply from a higher DC input for microcontrollers, sensors and logic circuits. It includes current limiting and thermal shutdown. Use at least a 10µF tantalum capacitor on the output.

What input voltage do I need for this regulator?
The input must be higher than 3.3V by the dropout voltage, about 1.2V at full 800mA load, so a input of roughly 4.5V or more is needed for full current. The extra voltage is dissipated as heat, so use a heatsink at high current or large input-output differences.
What are the pin connections of the TO-220 package?
In the fixed 3.3V version, pin 1 is GND, pin 2 is VOUT and pin 3 is VIN. The metal tab is connected to the output, so isolate it from grounded surfaces or use an insulating washer when mounting on a heatsink.
