Three Terminal Adjustable Output
Positive Voltage Regulators
LM317L3
The LM317L3 is an adjustable 3–terminal positive voltage regulator capable of supplying in excess of
1.5A 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 blow–out proof.
The LM317L3 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 LM317L3 can be used as a precision current regulator.

Cin is required if regulator is located an appreciate
distance from power supply filter.

Cout is not needed for stability, however, it does
improve transient response.
