(1) Input capacitors must be placed as close as possible to the device pins.
(2) When DC voltage is applied to a ceramic capacitor, the effective capacitance is reduced due to DC bias effect. The table above therefore lists the minimum value as CAPACITANCE. In order to meet the minimum capacitance requirement, the nominal value of the capacitor may have to be scaled accordingly to take the drop of capacitance into account for a given dc voltage at the outputs of regulators.
(3) Ceramic capacitors recommended
(4) Additional capacitance, including local and POL, beyond the specified value can cause the LDO to become unstable
