THREE–TERMINAL

ADJUSTABLE POSITIVE

VOLTAGE REGULATOR

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.

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.
