DESCRIPTION The LM217L/LM317L are monolithic integrated circuit in SO-8 and TO-92 packages intended for use as positive adjustable voltage regulators. They are designed to supply until 100 mA of load current with an output voltage adjustable over a 1.2 to 37V 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
