About this manual

The LM217M and LM317M are monolithic integrated circuits designed as positive adjustable voltage regulators. They supply up to 500 mA of load current with an output voltage adjustable from 1.2 V to 37 V, selected by a resistive divider. The devices feature thermal overload and short-circuit protection and are available in TO-220, DPAK, SOT-82, and SOT-194 packages.
