Hi to the list , Does any one have a data sheet or a link to one, for an MC1460 voltage regulator?
The voltage regulator board in my krautkramer USIP11 ultrasonic test set has failed and I suspect the above IC but I have no info at all on this IC, an extensive google search has revealed no info. Maybe some one has this info. My motorola data books only go back to 1979, and I think this IC is circa 1970.... The unit was made in 1976 ( and has been extremely reliable...) most of the components in it are from the early '70's. shades of AO7!
Any replies off list if you prefer,
Thanks Don, ZL1THO
Hi Don, ZL1THO
I have used a variable voltage regulator MC1460 back in 1973 to get a precise +3.6 V at 0.5 A for my homebrewed APT receiver.
Looking back in my papers I have found the schematic diagram and the 9 pin connections.
I will send to you a scanned copy of it.
By the way in my circuit:
Pin 3 = unregulated input = +20 volt DC
Pin 1 is connected to pin 4 via a 0.8 ohm limiting resistor
Pin 4-5 connected in parallel = regulated voltage +3.6 volt DC
The above variable voltage regulator was a most early in 1973 but if it failed and having the pin connections of it you can replace a MC1460 with a LM317 with minor circuit changes.
