LM317

Description

The LM117 series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 1.5A over a 1.2V to 37V output range. They are exceptionally easy to use and require only two external resistors to set the output voltage.

Key Features

  • Guaranteed 1% output voltage tolerance (LM317A)
  • Guaranteed max. 0.01%/V line regulation (LM317A)
  • Guaranteed max. 0.3% load regulation (LM117)
  • Guaranteed 1.5A output current
  • Adjustable output down to 1.2V
  • Current limit constant with temperature
  • P+ Product Enhancement tested
