This is the basic LD1117V33 voltage regulator, a low drop positive regulator with a 3.3V fixed output voltage. This fixed regulator provides a great amount of stability and protection for your project and with its on chip trimming this regulator is able to reach an output voltage tolerance within ±1%. Each one of these voltage regulators can output a max current of 800mA.
