September 2009
The maximum allowable power dissipation of any T
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 product only.
Enable pin should not be left open.
Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
