Product Overview

The LM317AMDT/NOPB is an adjustable 3-terminal Positive-Voltage Regulator capable of supplying current in excess of 1.5A over a 1.25 to 37V output range and provide 1% output-voltage accuracy. The device is ideal for space-constrained applications that require high-performance regulation. The device is exceptionally easy to use and requires only two external resistors to set the output voltage. Both line regulation and load regulation are better achieved with the device than with standard fixed regulator. The device offers full overload protection such as current limit, thermal-overload protection and safe-area protection. All overload protection circuitry remains fully functional even if the adjustment terminal is disconnected. An optional output capacitor can be added to improve transient response. The adjustment terminal can be bypassed to achieve very high ripple-rejection ratios that are difficult to achieve with standard 3-terminal regulator.
  • Current limit constant with temperature
  • Short-circuit protected output
  • 1% Output voltage tolerance
  • Typical 0.005%/V line regulation
  • Green product and no Sb/Br
