KK317

      The KK317 is a kind of 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.The voltage regulator is easy to use and requires only two external resistors to set the output voltage.Besides,it employs internal current limiting, thermal shutdown and safe area compensation,making them essentially blow-out proof.
