Electrical Characteristics
V
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, 1.5kΩ in series with 100pF.
4. Specification for packaged product only.
5. Both VIN and VBIAS UVLO thresholds must be met for the output voltage to turn-on. If either of the two input voltages is below the UVLO thresholds,
