Yes, LT's a possibility. Also MAXIM with less parts count. Check out the 680/681.

I'll go this route only if I don't find the MB3778.
Thanks

Reply to: >> No pettiness taken, But don't you think the manufacturer would have come up with that? ;-) I need it to be BIPOLAR 5 volts with ground common to the input ground. You better have another look at the datasheet.

Ahh! You meant +/- 5V. Silly me.
In that case you could use a 78L05/LT1054 combo or the LT1945 boost/inverter.
The first choice is simpler to put together, but the LT1054 needs extra room
for good tantalum caps.
The second choice is a little more complicated because you need additional
resistors to set both outputs, but it gives you up to 300mA on each rail.
