PRODUCTION DATA.
There is an internally fixed undervoltage shutdown threshold. Undervoltage shutdown activates when the input voltage on VIN drops below V(VinUVLO). This ensures the regulator is not latched into an unknown state during low input supply voltage. If the input voltage has a negative transient which drops below the UVLO threshold and recovers, the regulator shuts down and powers up with a normal power-up sequence once the input voltage is above the required levels.
