Product Overview

The LM317DCY is an adjustable three-terminal positive Voltage Regulator, capable of supplying more than 1.5A over an output-voltage range of 1.25 to 37V. It requires only two external resistors to set the output voltage. The device features a typical line regulation of 0.01% and typical load regulation of 0.1%. It includes current limiting, thermal overload protection and safe operating area protection. Overload protection remains functional even if the ADJUST terminal is disconnected.
  • Output Voltage Range Adjustable
  • Internal Short-circuit Current Limiting
  • Thermal Overload Protection
  • Output Safe-area Compensation
  • Green Product, No Sb/Br
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.
