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.
Line regulation measures a change in output voltage due to a change in the bias voltage.
Current measured from bias input to ground.
Current differential between output current and main input current at rated load current.
