3-TERMINAL ADJUSTABLE REGULATOR
LM317L / LM317LF
DESCRIPTION
The LM317 is an adjustable 3-terminal positive voltage regulator capable of
supplying 100mA over a 1.2V to 37V output range. It 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. Also, the LM317 is available packaged in a standard
TO-92 transistor package which is easy to use.
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.
