Linear RegulatorAdjustablePositive

The LM317S is a versatile, adjustable 3-terminal positive voltage regulator capable of delivering over 1.5A across a 1.2V to 37V output range.

Best for

  • Adjustable power supplies
  • General-purpose linear regulation

Avoid if

  • High-efficiency requirements (use switching regulators instead)
  • Very low dropout voltage applications

Check before use

  • Heat sink requirements for high power dissipation
  • Input/output capacitor placement
