Output Capacitor, Recommended Specifications
(Continued)
Note 15:
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. However, dependent on application, X5R,
Y5V, and Z5U can also be used. (See capacitor section in Applications Hints)
