REF2940: REF2940 class 1 capacitors

Part Number: REF2940

HI Guys

Datasheets suggests using larger capacitor, If a design needs to incorporate only class 1 capacitors, would the stability of the REF2940 output be greatly affected if a 10 nF capacitor used at the output?

Thanks

    Hi Rodney,

    The REF2940 is stable with no capacitor up to a low-ESR capacitance of 10 μF or less. The low-esr is typically reserved for ceramic capacitors.

    A 10nf can be used at the output. There is no requirement to use a larger capacitor.
