Description

General part information

LM317 Series

The LM317L is an adjustable, 3-terminal, positive-voltage regulator capable of supplying up to 100 mA over an output-voltage range of 1.25V to 37V. The device is exceptionally easy to use and requires only two external resistors to set the output voltage.

For the legacy chip, the LM317LC series is characterized for the junction temperature range of 0°C to +125°C and the LM317LI device is characterized for the operating junction temperature range of –40°C to +125°C. For the new chip, the both LM317LC and LM317LI series are characterized for the junction temperature range of –40°C to +125°C.
