Description

Description
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.
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
