LOW CURRENT

THREE–TERMINAL

ADJUSTABLE 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

1.2 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 blow–out proof.

SEMICONDUCTOR

TECHNICAL DATA

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.
