Hello all

Let me ask you a question about LMZ31503.

Required output capacitance is written on datasheet P12 , however is this value took account of DC Bias characteris of capacitor ? In the case of ceramic capacitors ,a capacitance of Cout decreases as Vout rise .

Best regards.

Hi Taichi,

Yes, the value of required output capacitance takes into account the DC Bias of the ceramic caps. Use the amount of capcitance shown in the table. You do NOT have to add more for actual capacitance due to DC Bias.
