AS1310 − Electrical Characteristics

Note(s) and/or Footnote(s):

1. The regulator is in startup mode until this voltage is reached. Caution: Do not apply full load current until the device output > 1.75V.

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

- The voltage at the LBI pin is below LBI threshold.
