LM317C

LM317C is a three terminal positive voltage regulator with maximum 1.5A current output and adjustable output. The voltage regulator is very easy to use, which only needs two external resistors to set the output voltage, and the output voltage can be set in the range of 1.2V to 37V. In addition, the LM317C is also designed to integrate internal current limiting, thermal shutdown and safe working area compensation, which makes it relatively difficult to damage and basically prevent the burning of circuit fuses. LM317C serves a variety of applications, including local voltage stabilization and card voltage stabilization. It can also be used to make a programmable voltage regulator, or as a precision current regulator by connecting a fixed resistance between the adjustment point and the output.
