Product Summary

The LM317 is an adjustable 3-terminal positive voltage regulator. It is capable of supplying in excess of 1.5A over a 1.2V to 37V output range. The LM317 is exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulation are better than standard fixed regulators. Also, the LM317 is packaged in standard transistor packages which are easily mounted and handled.

Parametrics

LM317 absolute maximum ratings: (1)Power Dissipation: Internally Limited; (2)Input-Output Voltage Differential: +40V, -0.3V; (3)Storage Temperature: -65 to +150℃; (4)Lead Temperature, Metal Package (Soldering, 10 seconds): 300℃; (5)ESD Tolerance: 3 kV.
