So if the designer adds an operating temperature of 40°C and a life expectancy of >=7 years, solve using equation 3 to determine the capacitance and ESR requirements at these conditions. Using the rule of thumb the designer will use a 30% capacitance reduction and 100% increase of ESR into the calculations. The result is 8.16 V which is higher than the calculated dVTotal of 7 V, this solution will not work.
