The  IL317L  is an adjustable 3-terminal positive voltage regulator capable of supplying in excess of 100 mA over an output voltage range of 1.2 Vto 37 V. This voltage  regulator  is  exceptionally  easy  to  use  and  requires  only  two  external resistors  to  set  the  output  voltage.  Further,  it  employs  internal  current  limiting,
thermal  shutdown  and  safe  area  compensation,  making  them  essentially  blow  – out proof.
