Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
The maximum allowable power dissipation of any T A (ambient temperature) is P D(MAX) = (T J(MAX) ? T A ) ÷ θ JA . Exceeding the maximum allowable power
dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k ? in series with 100pF.
Specification for packaged parts only.
Output voltage temperature coefficient is defined as the worst-case voltage change divided by the total temperature range.
Regulation is measured at constant junction temperature using pulse testing with a low duty cycle. Changes in output voltage due to heating effects
are covered by the speculation for thermal regulation.
Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal value measured at
V IN =V OUT +1V.
