I plan to use the LD1086DT33TR LDO to output 3.3V with an input voltage of 5V. However, I am not aware of the requirements for the ESR (Equivalent Series Resistance) of the output filter capacitor for the LD1086DT33TR, and this parameter is not mentioned in the datasheet. I intend to use either the GRM31CZ71C226ME15L or the CC1206KKX7R6BB226 as the output filter capacitor, and I am considering using two such capacitors in parallel. I wonder if this configuration is appropriate.(Or a 25YXF47MFFC5X11)?
