These came to us as part of a lot of surplus stock from a large ‘Milspec’ type Co. and have been kept in storage for many years (date coded 143 our guess is ’81) they were stored loosely in a Linbin and may have picked up the odd cosmetic mark or a spot of or two of oxidisation, we have therefore classified them as ‘new other’. They are however in good serviceable condition, they have been tested and ticked with marker (bag marked ‘tested OK june 08’) prior to our purchase, and remember we offer a full guarantee on all our items. At the time of listing we have 5 left in stock see photographs.

The LM323 are three-terminal positive voltage
regulators with a preset 5V output and a load
driving capability of 3A. New circuit design and
processing techniques are used to provide the
high output current without sacrificing the
regulation characteristics of lower current
The 3A regulator is virtually blowout proof.
Current limiting, power limiting and thermal shutdown provide high level of reliability. An overall
worst case specification for the combined effects
of input voltage, load current, ambient
temperature, and power dissipation ensure that
the LM323 will perform satisfactorily as a system
