Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
Specification for packaged product only
Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature change.
Dropout voltage is defined as the input-to-output differential when output voltage drops to 99% of its normal value with V

Thermal regulation is defined as the change in the output voltage at a time T after a change in power dissipation is applied, excluding load or line
regulation effects. Specifications are for a 250mA load pulse at V
