1.5 A Adjustable Output,
Positive Voltage Regulator
The LM317 is an adjustable 3terminal 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 blowout 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.
