How does LM317 work?

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. 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%.

Why LM317 is called so?

It is also called a temperature-independent reference voltage frequently used in integrated circuits. An error term is added because some quiescent current flows from the adjustment pin of the device. Hence, this LM317 circuit can be treated as LM317 Current Regulator Circuit.

What is then the LM317 IC is all about?

The LM317 is an adjustable 3−terminal positive voltage regulator capable of supplying in excess of 1.5 A over an output voltage range of 1.2 V to 37 V. This voltage regulator is exceptionally easy to use and requires only two external resistors to set the output voltage.

Is LM317 stable?

The LM317 has three pins: INput, OUTput, and ADJustment. Internally the device has a bandgap voltage reference which produces a stable reference voltage of Vref= 1.25 V followed by a feedback-stabilized amplifier with a relatively high output current capacity.
