  • The LM217L/LM317L are monolithic integrated circuits in SO-8 and TO-92 packages intended for use as positive adjustable voltage regulators. They are designed to supply up to 100 mA of load current with an output voltage adjustable over a 1.2 to 37 V range.The nominal output voltage is selected by means of only a resistive divider, making the device exceptionally easy to use and eliminating the stocking of many fixed regulators.

    Key Features

    • Outuput voltage range: 1.2 to 37 V
    • Output current up to 100 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
