Anyone know of something like an LM385 in a SOD123 package?
The voltage isn't very critical but a low dynamic impedance is reasonably important. It's function is to set the current for an opto-isolator (resistor can be changed) but really should be at the high end of the 1.25-2.5V range at 1mA. The LM185-2.5 that's supposed to go in there is a SOT-23. Oops!
