• Output adjustable between 1.25V & 37V• Internal thermal overload protection• Internal short circuit current limiting constant with temperature• Output transistor safe-area compensation• Floating operation for high voltage applications• Eliminates using many fixed voltages• Output voltage with 4% tolerance The LM317 is an adjustable, positive, 3-terminal voltage regulator capable of supplying 1.5A over an output voltage range of 1.2V to 37V. This voltage regulator is exceptionally easy to use & require only 2 external resistors to set the output voltage. Both line & load regulation are better than standard fixed regulators. Full overload protection is included on-chip with current limiting, thermal & safe area protection. This remains fully functional even if the adjustment terminal is disconnected, making it essentially blow-out proof. Supplied in a TO-263 style case.
