Hi All,

I am repairing a very old 2way radio and I am looking for a Motorola
MFC-6030 regulator IC,
(there is nothing at ON-Semi of course).

Help
1. I am looking for the data sheet for the MFC-6030

2. I am looking to purchase 1~10pcs at moderate cost

3. I am looking for suggested replacements with the same pin out,

(eg I think the MFC-6030A MFC-6034 are such replacement)

Any pointers to where I might be able to get these would be
appreciated.


Thanks in advance
Joe

Surprisingly, I have the MFC6030A datasheet in an old Motorola
catalog...

1. gnd
2. unreg input (38V max, much less for 6034)
3. output (35V max)
4. current sense (200 mA max)
5. compensation? .001uf to gnd
6. voltage sense across divider resistors, Vref?

I strongly suggest tat you drop the idea of "pin-out" replacement
and/or buying such an obsolete part - unless you like $$pending a LOT of
money.
Use a superior regulator still in production: the UA723 (takes a lot
less parts).

I can do one or two of MFC6030A, if you're stuck.

Nosing around some ham-radio sites seems to suggest an LM317 as a
reliable/stable/economic replacement.

Yeah, but there's nothing like a bit of authenticity in some of these
lovely old things. Might not even weigh a ton, or have lost all of its
plastic bits, if it's the right vintage.

In those days, not just anyone took the leap of faith, with that
particular series of parts.
