Note 1:
All units are 100% production tested at T
A
=+25
°
C. Limits over the operating temperature range are guaranteed by design
and not production tested.
Note 2:
Supply current into OUT. This current correlates directly to the actual battery-supply current, but is reduced in value accord-
ing to the step-up ratio and efficiency.
