Note 1:

Start-up voltage operation is guaranteed without the addition of an external Schottky diode between the

input 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 bat-

tery supply.
