Note 4:
Minimum VIN operation after start-up is only limited by the specifications from 0°C to 70°C. Specifications over the – 30°C to 85°C battery’s ability to provide the necessary power as it enters a deeply operating temperature range are assured by design, characterization and discharged state. correlation with statistical process controls.
Note 5:
Burst Mode operation IQ is measured at VOUT. Multiply this value by VOUT/VIN to get the equivalent input (battery) current. 3400fa 2
