PRODUCTION DATA
The device has an internally fixed undervoltage lockout threshold. Undervoltage lockout activates when the input voltage VIN drops below the undervoltage lockout (UVLO) level; see the VUVLO(FALLING) parameter in the Electrical Characteristics table. This activation makes sure the regulator is not latched into an unknown state during a low input supply voltage. If the input voltage has a negative transient that drops below the UVLO threshold and recovers, the regulator shuts down and powers up in the standard power-up sequence when the input voltage recovers to the required level (see the VUVLO(RISING) parameter in the Electrical Characteristics table).
