LM317LM is a positive voltage regulator manufactured by National Semiconductor (NC).

The LM317LM is a positive voltage regulator manufactured by National Semiconductor (NC).

Specifications:

  • Output Voltage Range: 1.2V to 37V
  • Output Current: Up to 100mA
  • Input-Output Voltage Differential (Dropout Voltage): 3V (max)
  • Line Regulation: 0.01%/V (typ)
  • Load Regulation: 0.1% (typ)
  • Operating Temperature Range: 0°C to +125°C
  • Package: TO-220

Descriptions:

The LM317LM is a three-terminal adjustable positive voltage regulator designed to supply at least 100mA of output current. It requires only two external resistors to set the output voltage and features internal current limiting, thermal shutdown, and safe operating area protection.

Features:

  • Adjustable output voltage
  • Internal thermal overload protection
  • Short-circuit protection
  • Output transistor safe operating area protection
  • Low standby current
  • 1% output voltage tolerance (LM317LM)

This regulator is commonly used in power supply circuits requiring a stable and adjustable voltage source.
