供应 LM317M ST稳压芯片

LM317M DESCRIPTION

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