Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k ? in series with 100pF.
4. Specification for packaged product only.
5. For V OUT ≤ 1V, V BIAS dropout speci ? cation does not apply due to a minimum 3V V BIAS input.
6. I GND = I BIAS + (I IN – I OUT ). At high loads, input current on V IN will be less than the output current, due to drive current being supplied by V BIAS .
7. Fixed output voltage versions only.
