Notes
1. Mostly dependent on the maximum required Tamb 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 Tamb = 75 °C and a maximum
junction temperature of 125 °C.
