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. Further, it employs internal

current limiting, thermal shutdown and safe area compensation, making it

essentially blow–out proof.

THREE–TERMINAL

ADJUSTABLE POSITIVE

VOLTAGE REGULATOR

The LM317 serves a wide variety of applications including local, on card

regulation. This device can also be used to make a programmable output

regulator, or by connecting a fixed resistor between the adjustment and

output, the LM317 can be used as a precision current regulator.

ORDERING INFORMATION

Operating

** C is required if regulator is located an appreciable distance from power supply filter.

** C is not needed for stability, however, it does improve transient response.
