Product Overview

The LM317AT/NOPB is an adjustable 3-terminal positive Voltage Regulator, capable of supplying in excess of 1.5A over a 1.2 to 37V output range. It is exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulations are better than standard fixed regulators. In addition to higher performance than fixed regulators, the LM317AEMP/NOPB series offers full overload protection available only in IC's. Included on the chip are current limit, thermal overload protection and safe area protection. All overload protection circuitry remains fully functional even if the adjustment terminal is disconnected.
  • Specified 1% Output Voltage Tolerance
  • Specified Maximum 0.01%/V Line Regulation
  • Specified 1.5A Output Current
  • Adjustable Output Down to 1.2V
  • Current Limit Constant with Temperature
  • P+ Product Enhancement Tested
  • 80dB Ripple Rejection
  • Output is Short-circuit Protected
  • Green Product, No Sb/Br


Automation & Process Control
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
