ELECTRICAL
CHARACTERISTICS
Parameter
The minimum V
V
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 at a 1V differential.
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
dissipation causes the device to initiate thermal shutdown. Please see Section 5.1, “Thermal Considerations”, for
more details
