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. Guaranteed by design and/or testing of related parameters. Not 100% tested in production.
5. The MIC3003 will attempt to enter its shutdown state when V
DD
falls below V
UVLO
. This operation requires time to complete. If the supply voltage falls
too rapidly, the operation may not be completed.
6. Does not include quantization error.
