What is the maximum capacitance recommended for Vbb?

thanks,

    Hi Joey,

    The recommended value for VBB in the datasheet is 10nF. I don't have test data for maximum value. I will check with my team internally to see if we have simulation data for this and get back to you.

    Hi Joey,

    You can use higher capacitance value than 10 nF which would result in longer time for reference output to stable. This reference has a 70 ohm resistor on the output path so you can calculate the time to stable based on your capacitance value.
