Relative variation of thermal impedance junction to ambient versus pulse duration is given for all of the switches offered by ST. Is this only for one single pulse or continuous pulses need to use this diagram as well? For example from this graph, if...

In the application note for one of ST parts (L4981BD) and it is mentioned that the output voltage can be calculated from the following formula:   But in the datasheet, in Figure 9B, the given output voltage does not match with this formula: Does anyo...
