Storage temperature range
Operating ambient temperature range
Junction temperature
Notes
1. Mostly dependent on the maximum required T
amb
and on the voltage between LN and SLPE.
See Figs 7 and 8 to determine the current as a function of the required voltage and the
temperature.
2. Calculated for the maximum ambient temperature specified T
amb
= 75
°C
and a maximum
junction temperature of 125
°C.
