Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range
from 0.1 mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the thermal
regulation specification.
Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value.
Thermal Regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load or
line regulation effects. Specifications are for a current pulse equal to I
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
thermal shutdown. Please see Section 5.0 “Thermal Considerations” for more details.
Hysteresis voltage is referenced by V
Apply for Junction Temperatures of -40°C to +85°C.
