= -40°C to +85°C
, unless otherwise noted.) (Note 4)
Note 1:
Start-up voltage operation is guaranteed with the addition of a Schottky MBR0520 external diode between the input and
output.
Note 2:
Steady-state output current indicates that the device maintains output voltage regulation under load. See Figures 5 and 6.
Note 3:
Device is bootstrapped (power to the IC comes from OUT). This correlates directly with the actual battery supply.
