National Semiconductor LM317HVK High Voltage Regulator
These are the high voltage version of the standard LM 317K
Package style 3 pin TO3 in steel
Date code H8444 BUT IN PERFECT “AS NEW” CONDITION
3-Terminal Adjustable Regulator
The LM317HV is an adjustable 3-terminal positive
voltage regulator capable of supplying in excess of 1.5A
over a 1.2V to 57V output range. They are exceptionally
easy to use and require only two external resistors to set the
output voltage. Further, both line and load regulation are better than standard fixed regulators.
The LM317HVK STEEL is packaged in standard TO-3 transistor package
Adjustable output down to 1.2V
Guaranteed 1.5A output current
Line regulation typically 0.01%/V
Load regulation typically 0.1%
Current limit constant with temperature
100% electrical burn-in
Eliminates the need to stock many voltages
Standard 3-lead transistor package
80 dB ripple rejection
Output is short-circuit protected
P+ Product Enhancement tested
THESE CAME TO US AS PART OF A “JOB LOT” OF SURPLUS STOCK ORIGINATING FROM A LARGE MILSPEC TYPE OEM. THEY ARE DATE CODED H8444, – AN ANTIQUE SEMICONDUCTOR ???
Having been in storage for many years we have classified them as ‘new other’ but they are in perfect condition.
IDEAL IF YOU ARE LOOKING FOR AUTHENTIC PARTS FOR A RENOVATION PROJECT.
