#178449 - Yes, that's National Semiconductor
Responding to: ???'s previous message

Chico Magalhães said:

But when you try to get the datasheet is a deception!

No deception!

Think about it: there is a whole range of 78Hxx regulators, isn't there?
The only real difference between them is the "xx" output voltage, isn't it?

And, as already noted, there may be a suffix denoting different packages - in this case, 'K' indicates the TO3 package.

So you shouldn't expect to find a separate datasheet for each different "xx" output voltage and, for each of them, a separate datasheet for each different package!

Instead, you will get a "Family" datasheet that covers the whole 78Hxx range!

               I think the "H" may be because it is 5A isnt it?              01/01/70 00:00

   these parts are hybrids ... so you can synthesize them              01/01/70 00:00
