Note 1: Exceeding the absolute maximum rating may damage the device.
Note 2: The device is not guaranteed to function outside its operating rating.
Note 3: The maximum allowable power dissipation at any TA (ambient temperature) is calculated using: PD(max) = (TJ(max) - TA)/θJA
.
Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into
thermal shutdown. See the “Thermal Considerations” section for details.
Note 4: Output voltage temperature coefficient is the worst-case voltage change divided by the total temperature
range.
Note 5: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load
regulation in the load range from 100µA to 1A. Changes in output voltage due to heating effects are covered by the thermal
regulation specification.
Note 6: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value
measured at 1V differential.
