The IL317 is adjustable 3-terminal positive voltage  regulator capable of supplying in excess of 1.5 A over an
output voltage range of 1.2 V to 37 V. These voltage regulator is exceptionally easy to use and require only two external resistors to set the output voltage. Further, it employ internal current limiting, thermal shutdown and safe area compensation, making them essentially blow-out proof.
