1. If the input voltage falls below this value during normal operation the device goes in startup mode.

2. The regulator is in startup mode until this voltage is reached. Caution: Do not apply full load current until the

device output > 2.3V

3. LBO goes low in startup mode as well as during normal operation if:

1) The voltage at the LBI pin is below LBI threshold.

2) The voltage at the LBI pin is below 0.1V and V

OUT

is below 92.5% of its nominal value.
