What is the line regulation of the LM317?
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%.
What can a LM317 pinout be used for?
It can be used as a fixed voltage regulator, AC voltage regulator, current limiter, Battery charger, local and on-card regulation. Furthermore, it can be used as a current regulator by connecting a resistor between the output and adjustment pin. It has one drawback that during regulation its voltage drop to about 2.5V.

How is the output of a LM317 IC adjusted?
The LM317 IC develops and maintains 1.25V between its output and adjustment pin. Its output can be adjusted by connecting a network of two resistors externally between the output pin and adjust the input pin. The two decoupling capacitors are connected in a circuit. They are used to remove the undesired coupling and avoid the effect of noise.
What is the reference voltage of the lm217, LM317?
The LM217, LM317 provides an internal reference voltage of 1.25 V between the output and adjustments terminals. This is used to set a constant current flow across an external resistor divider (see Figure 6. Basic adjustable regulator), giving an output voltage VOof: VO= VREF(1 + R2/R1) + IADJR2
What kind of voltage regulator does STMicroelectronics use?
The LM217, LM317 are monolithic integrated circuits in TO-220, TO-220FP and D²PAK packages intended for use as positive adjustable voltage regulators. They are designed to supply more than 1.5 A of load current with an output voltage adjustable over a 1.2 to 37 V range.
