The LM317 is an adjustable, positive, 3-terminal voltage regulator capable of supplying 100mA (Order Code RA87U) or 1.5A (Order Codes UF27E and N61CA) over an output voltage range of 1.2V to 37V. These voltage regulators are exceptionally easy to use and require only 2 external reistors to set the output voltage. Both line and load regulation are better than standard fixed regulators. Full overload protection is included on-chip with current limiting, thermal and safe area protection. This remains fully functional even if the adjustment terminal is disconnected, making it essentially blow-out proof.
Order Code UF27E is supplied in a TO-220 style case.
Order Code RA87U is supplied in a TO-92 style case.
Order Code N61CA is supplied in a TO-263 style case.
