1. The regulator is in startup mode until this voltage is reached.

Caution:

Do not apply full load current until the device output > 2.5V

2. LBO goes low in startup mode as well as during normal operation if,

(i) The voltage at the LBI pin is higher than LBI threshold.

(ii) The voltage at the LBI pin is below 0.1V (connected to GND) and VOUT is below 92.5% of its nominal value.

3. Further switching is inhibited.
