The LM317DCY is an adjustable three-terminal positive Voltage Regulator, capable of supplying more than 1.5A over an output-voltage range of 1.25 to 37V. It requires only two external resistors to set the output voltage. The device features a typical line regulation of 0.01% and typical load regulation of 0.1%. It includes current limiting, thermal overload protection and safe operating area protection. Overload protection remains functional even if the ADJUST terminal is disconnected.

The LM317 device is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V.
An adjustable voltage regulator is a regulator that can be adjusted to output any voltage from the range that the voltage regulator is designed to output. A LM317T voltage regulator, which is what we are going to use in this setup, can be adjusted to output from +1.2V to 37V.
The main limitation is that, in effect, it's an elaborate resistor. As such it's a very wasteful, inefficient way to regulate voltage, and it throws away a lot of energy as heat.
