Product overview

Description

The LM217M and LM317M are monolithic integrated circuits in DPAK package used as positive adjustable voltage regulators. They are designed to supply until 500 mA of load current with an output voltage adjustable over a 1.2 to 37 V range. The nominal output voltage is selected by one resistive divider only, making the device exceptionally easy to configure and avoiding the use of several fixed regulators.
  • All features

    • Output voltage range: 1.2 to 37 V
    • Output current in excess of 500 mA
    • Line regulation typ. 0.01%
    • Load regulation typ. 0.1%
    • Thermal overload protection
    • Short-circuit protection
    • Output transition safe area compensation
    • Floating operation for high voltage applications
