[sdiy] Question about LM336

[David G Dixon]

Yes, Oren, I gave this some thought, and I think I'm seeing it more clearly
now.  All I have to do is make sure that the source current is a bit higher
than the expected current draw, and that this value does not exceed about 10
mA.  That should be easy enough to figure out.

[CAUTION: Non-UBC Email]	

I use LM336 and other shunt references such as LM4040-x and LM329
unbuffered. Most everything I use these references for requires only a few
mA max. If I think more current is needed, I'll lower the series resistor a
little.

Hey SDIY Team,
 
Here's a quick technical question about the LM336 5V voltage reference.
 
Do you ever use it without an opamp buffer?  I have always buffered it, but
I'm gathering that this is not strictly necessary.
 
Cheers,
Dave Dixon
