Description
National Semiconductor LM317K Voltage Regulator
Package style 3 pin TO3 in steel
Date code H8508 BUT IN PERFECT “AS NEW” CONDITION
Description
The SG317K is a monolithic integrated circuit in a TO-3 style package intended for use as a positive adjustable voltage regulator.They are designed to supply more than 1.5 A 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.

THESE CAME TO US AS PART OF A “JOB LOT” OF SURPLUS STOCK ORIGINATING FROM A LARGE MILSPEC TYPE OEM. THEY ARE DATE CODED H8508, IF THERE IS SUCH A THING AS AN ANTIQUE SEMICONDUCTOR I BELIEVE THESE QUALIFY!
IDEAL IF YOU ARE LOOKING FOR OLD SEMI’S TO GIVE AUTHENTICITY TO A RENOVATION PROJECT- PLEASE NOTE DUE TO THEIR AGE WE HAVE CLASSIFIED THEM AS “NEW OTHER” THOUGH THEY ARE IN PERFECT CONDITION.
