Description:
The UA7924UC fixed–voltage regulator is a monolithic integrated circuit in a TO220 type package designed for use in a wide variety of applications including local, on–card regulation. This regulator employs internal current limiting, thermal shutdown, and safe–area compensation. With adequate heat sinking it can deliver output currents in excess of 1A. Although designed primarily as a fixed regulator, this device can be used with external components to obtain adjustable voltages and currents.

These genuine vintage parts came to us as part of a lot of surplus stock from a large ‘Milspec’ type Co.
Having been in storage for many years (date coded 8001) we have classified them as ‘new other’.
