REF3025: REF3025

Part Number: REF3025
Other Parts Discussed in Thread: REF3012

What is the maximum capacitive load at the output of REF3025.

In the circuit are 10uF/X/R in parallel with 10nF/C0G. Is this ok?

Thanks

    Hi Heini,

    section 9.1 of datasheet of REF3025 recommends an output capacitance of less than 10µ for REF3012. It's wise to follow this recommendation also for the REF3025. An additional 10n/NP0 in parallel to the 10µ/X7R isn't needed, usually. Connect the 10µ/X7R output cap directly to the chip.

    Hi Heini,

    Kai referenced the correct section in the datasheet. The 10nF is not needed. Just make sure not to exceed 10uF with low ESR. The REF3025 is stable without  a capacitor.
