LM317 Datasheet
The LM317 datasheet specifies that 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 is exceptionally easy to use
and requires only two external resistors to set the output voltage.
Furthermore, both line and load regulation are better than standard
fixed regulators.
The LM317 is versatile in its applications, including uses in
programmable output regulation and local on-card regulation. Or, by
connecting a fixed resistor between the ADJUST and OUTPUT terminals, the
LM317 can function as a precision current regulator. An optional output
capacitor can be added to improve transient response. The ADJUST
terminal can be bypassed to achieve very high ripple-rejection ratios,
which are difficult to achieve with standard three-terminal
regulators.
