Note 5.
Exceeding maximum rating may damage the device.
The device is not guaranteed to work 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.
Specification for packaged product only.
Minimum input for line regulation test is set to V OUT + 1V relative to the highest output voltage.
