Load regulation is measured at a constant junction temperature using low duty-cycle pulse testing. Load
regulation is tested over a load range from 1 mA to the maximum specified output current.
Dropout voltage is defined as the input-to-output voltage differential at which the output voltage drops 2%
below its nominal value that was measured with an input voltage of V
The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
junction temperature and the thermal resistance from junction to air. (i.e., T
mum allowable power dissipation will cause the device operating junction temperature to exceed the maxi-
mum 150°C rating. Sustained junction temperatures above 125°C can impact device reliability.
The junction temperature is approximated by soaking the device under test at an ambient temperature
equal to the desired junction temperature. The test time is small enough such that the rise in the junction
temperature over the ambient temperature is not significant.
