LM317MX中文资料意法半导体数据手册PDF规格书

DESCRIPTION

The LM217M/LM317M are monolithic integrated circuits in TO-220, DPAK, SOT-82 and SOT-194 packages intended for use as positive adjustable voltage regulators.

They are designed to supply until 500 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.
