Note 2: Supply current from the 3.3V output is measured with an ammeter between the 3.3V output and OUT pin. This current
correlates directly with actual battery supply current, but is reduced in value according to the step-up ratio and efficiency.
V OUT = 3.47V to keep the internal switch open when measuring the current into the device.
Note 3: Minimum value is production tested. Maximum value is guaranteed by design and is not production tested.
