ST LM217L LM317L Low current 1.2 to 37V adjustable voltage regulator handbook
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 100mA of load current with an output voltage adjustable over a range of 1.2 to 37V. The device has a nominal output voltage selected by means of a resistive divider, making it easy to use and eliminating the need for stocking many fixed regulators. It features thermal overload protection, short circuit protection, and output transition safe area compensation. Floating operation is available for high voltage applications.
