LM317L, NCV317L
100 mA Adjustable Output,
Positive Voltage Regulator
The LM317L is an adjustable 3terminal positive voltage regulator
capable of supplying in excess of 100 mA 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 them essentially blowout proof.
The LM317L 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 LM317L can be used as a
precision current regulator.
