LM317T Datasheet


This monolithic integrated circuit is an adjustable 3-terminal positive voltage regulator designed to supply 2.2A typical of load current with an output voltage adjustable over a 1.2 to 37V. It employs internal current limiting, thermal shutdown and safe area compensation.


• Output-Current In Excess of 2.2 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
