Output Capacitor, Recommended Specifications
Note 17: The capacitor tolerance should be 30% or better over temperature. The full operating conditions for the application should be considered when selecting
a suitable capacitor to ensure that the minimum value of capacitance is always met. Recommended capacitor type is X7R or X5R. (See capacitor section in
Applications Hints)
Note 18: On lower voltage options, 2.2µF output capacitor may be used but some degradation in load transient (10 -15%) can be expected, compared to a 4.7µF.
