Load regulation is measured at a constant junction temperature using low duty cycle pulse testing. Changes in output
voltage due to heating effects are determined using thermal regulation specification TCV
Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal V
measured value. The nominal VR measured value is obtained with
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
dissipation will cause the device operating junction temperature to exceed the maximum 150°C rating. Sustained
junction temperatures above 150°C can impact the 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.
