Exceeding an absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
The maximum allowable power dissipation at any T A (ambient temperature) is P D(max) = (T J(max) – T A ) / θ JA . Exceeding the maximum allowable power
dissipation results in excessive die temperature, and causes the regulator to enter thermal shutdown.
Devices are ESD sensitive; use proper handling precautions.
Specifications are for packaged products only.
Line regulation is a percentage of V OUT .
