(Note 1)
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LTC3400E/LTC3400BE are guaranteed to meet performance
specifications from 0
°C to 70°C. Specifications over the –30°C to 85°C
operating temperature range are assured by design, characterization and
correlation with statistical process controls.
The q denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VIN = 1.2V, VOUT = 3.3V, unless otherwise specified.

ELECTRICAL CHARACTERISTICS
Note 3: Specification is guaranteed by design and not 100% tested in
production.
Note 4: Minimum VIN operation after start-up is only limited by the
battery’s ability to provide the necessary power as it enters a deeply
discharged state.
Note 5: Burst Mode operation IQ is measured at VOUT. Multiply this value
by VOUT/VIN to get the equivalent input (battery) current.
