The LM317A-337N-EVM demonstrates canonical application of the LM317A adjustable regulator and its negative complement, the LM337-N. The evaluation module is assesmbled with the SOT-223 package option for each device, supplying up to 1.0 A of load current. The EVM is designed for  easy modification to populate the TO-220 version devices for 1.5 A operation. Ample amount of footprint space has been provided for personal capacitor selection, along with 4 copper layers and heat sink space for excellent power dissipation.

  • OUTPUT Adjustable from 1.2 V to 37 V for LM317A and  −1.2V to  −37V for LM337-N
  • 1.0 A Load Current with 1.5 A option
  • Heat Sink Space Provided for TO-220
  • Large Capacitor Footprint Space for Customer Selection
