1.Description:
   LM317 as a good regulator with high stability, high temperature, high linearity and other characteristics, the output voltage range up to 1.25V~37V continuously adjustable, the maximum operating current of more than 1A (using a large radiator or Active cooling measures). The board with a rectifier bridge, and with a 3300uF filter capacitor, can effectively reduce the output ripple and interference.

2.Feature:
  1>. Linear voltage regulator LM317 voltage regulator module can stabilize the input DC voltage output;
  2>.The output voltage of LM317 ranges from 1.25V to 30V, and the maximum load current is 1.5A;
  3>.LM317 built-in overload protection, safety protection and other protection circuits. Typically, the LM317 does not require external capacitance, and the output capacitance can change the transient response;
  4>.The input voltage and output voltage of the module need to have a certain pressure difference, generally greater than 2V;
  5>.This upgrade has its own rectifier bridge, 3A 1000V voltage, support AC input.
