Part Number: LM334
Other Parts Discussed in Thread: TL1431-SP

Hi team,

customer is looking for space solution for current source application, LM334 can meet customer application however there is no space application.

If there is no LM334 space grade solution, can we suggest discrete solution? thanks.

Hi Eddie,

What current levels are needed for this application?

Is this current source or current sink?

The only space-rated adjustable voltage reference is the TL1431-SP.

For more complex, opamp-based current sources/sinks, see page 25 of Tips and tricks for designing with voltage references.
