Load Current (mA)
* AME specifies full temperature range
as -40^oC to +125^oC of junction tempera-
ture. Due to the difficulty of measuring
junction temperature, AME decides to
measure +125^oC of ambient tempera-
ture instead.
Heats DUT up to 125^oC ambient will
result in junction temperature to be
higher than +125^oC. A marginal failure
of Dropout Voltage vs Load Current is
negligible.
