1. Care should be taken when selecting the capacitor, due to its tolerance, as well as the parameter
dependency on temperature, DC bias and frequency in addition to other factors. The parameter
specifications must be respected for the full application range.
2. This frequency of 1 MHz as a condition for VCAP parameters is given by the design of the internal regulator.
