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.

5:

Dropout voltage is defined as the input-to-output voltage differential at which the output voltage drops 2% below its

6:

The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction

dissipation will cause the device operating junction temperature to exceed the maximum +150°C rating. Sustained

junction temperatures above +150°C can impact device reliability.

7:

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.
