[sdiy] Current sink/source specs LM336 vs. LM385

[Justin Owen]

Hello,

These guys: http://www.sdiy.org/juz/VRef_buffer.png

I'm trying to work out if there's a better VRef/Buffer combo between the LM336 2.5 vs. LM385 2.5 VRef and the TL072 vs LT1013 opamps as buffer.

Part of that is working out how much current the two combinations can source/sink.

I think both the TL072 and LT101 can sink/source between 20 and 25mA but I can't work out what the equivalent values are for the VRefs.

A VReg data sheet would generally give an 'Output Current' - but it doesn't seem like VRef sheets do.

Any clues?

Thanks,

- J
