(1) Effective value. Ceramic capacitor’s derating effect under bias should be considered. Choose the right nominal capacitance by checking capacitor DC bias characteristics.

(2) If LDO output current is lower than 20 mA, the minimum effective output capacitance value can be lower to 0.5 µF.

(3) With load switch version, the output capacitor at VSUB pin is only required if smaller voltage ripple is needed.
