The LM317 is a popular adjustable voltage regulator that can provide a stable output voltage ranging from 1.25V to 37V. It is widely used in power supply circuits due to its versatility, ease of use, and adjustable output voltage.

How the LM317 Works as a Voltage Regulator

The LM317 maintains a fixed reference voltage of 1.25V between its output (Vout) and adjustment (Adj) pins. By using a pair of resistors in a voltage divider configuration, the output voltage can be adjusted as needed.
