Table 3. Electrical Characteristics
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
3. LBO goes low in startup mode as well as during normal operation if:
Note: All limits are guaranteed. The parameters with min and max values are guaranteed with production tests or
