Note 1:
Start-up voltage operation is guaranteed without the addition of an external Schottky diode between the in-
put and output.
Note 2:
Steady-state output current indicates that the device maintains output voltage regulation under load.
Note 3:
Device is bootstrapped (power to the IC comes from OUT). This correlates directly with the actual battery
supply.
