Please could you tell me if there is a limit on the value and/or ESR of the
capacitor connected to the output of the ADR381. Are there any possible
stability implications of using low ESR ceramic capacitors (10 uF X5R)?

 

Looking into our technical information archives for this product I didn’t see
any material about the ESR of the output cap. So I checked with the designers :
they don't recall any experiments regarding ESR. We don't have any warnings
about ESR levels so you would need to try your desired capacitor in your
circuit with the load (ADC/DAC reference input, or whatever) you are planning
to place on the reference output.
