(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 maximum
value must be respected for the full application range.
(2)This frequency of 1 MHz as a condition for VCAP parameters is given by design of internal regulator.
(3)To calculate PDmax(TA), use the formula PDmax =(TJmax- TA)/ΘJA (see Thermal characteristics ) with the
value for TJmax given in the previous table and the value for ΘJA given in Thermal characteristics.
