LM317 Datasheet


This monolithic integrated circuit is an adjustable 3-terminal positive-voltage regulator designed to supply more than 1.5 A of load current with an output voltage adjustable over a 1.2 V to 37 V range. It employs internal current limiting, thermal shutdown, and safe area compensation.

• Output-Current In Excess of 1.5 A
• Output-Adjustable Between 1.2 V and 37 V
• Internal Thermal Overload Protection
• Internal Short-Circuit Current Limiting
• Output-Transistor Safe Operating Area Compensation
