Product Summary

The LM317EM is an adjustable 3-terminal positive voltage regulator. The LM317EM is capable of supplying in excess of 1.5A over a 1.2V to 37V output range. It is exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulation is better than standard fixed regulators.

Parametrics

LM317EM 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℃,Plastic Package (Soldering, 4 seconds):260℃; (5)ESD Tolerance: 3 kV.
