LM317L, NCV317LB

100 mA Adjustable Output,

Positive Voltage Regulator

The LM317L is an adjustable 3-terminal positive voltage regulator

capable of supplying in excess of 100 mA over an output voltage range

of 1.2ꢀV 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 blow-out 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.

ORDERING INFORMATION

See detailed ordering and shipping information in the package

dimensions section on page 10 of this data sheet.

ꢀ* C is required if regulator is located an appreciable

** C is not needed for stability, however,

** it does improve transient response.
