Product Summary

The LM317M is an adjustable 3-terminal positive voltage regulator. The LM317M is capable of supplying in excess of 1.5A over a 1.2V to 37V output range. The LM317M 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

LM317M absolute maximum ratings: (1)VI – VO Input-to-output differential voltage: 40 V; (2)TJ Operating virtual junction temperature: 150 ℃; (3)Lead temperature (within 5 mils of the plastic body for 10 s)KTP, DCY packages: 260 ℃; (4) Storage temperature range: –65 to 150 ℃.

Features

LM317M features: (1) Guaranteed 1% output voltage tolerance; (2) Guaranteed max. 0.01%/V line regulation; (3) Guaranteed 1.5A output current; (4) Adjustable output down to 1.2V; (5) Current limit constant with temperature; (6) P+ Product Enhancement tested; (7) 80 dB ripple rejection; (8) Output is short-circuit protected.
