Hello. I am reviewing a circuit in which the LM4132BMF-3.0/NOPB 3 Volt reference has been used with a larger output capacitor than input capacitor. The datasheet is explicit that this is not allowed:
The value of CIN must be sized according to the output capacitor value. The value of CIN must satisfy the relationship CIN ≥ COUT.
When no output capacitor is used, CIN must have a minimum value of 0.1 µF.
Is this restriction related to the question asked in <https://e2e.ti.com/support/power_management/linear_regulators/f/321/t/467130>, where the question was whether the reference would suffer reverse current if the output voltage was higher than the input voltage?
Is the LM4132 apt to be damaged if the output capacitor is 2 - 3 times larger than the input capacitor?
Thank you in advance,
