 UVLO is programmable using a resistor divider from VIN to ENL to AGND. The ENL voltage is compared to an internal reference.
(2) Guaranteed by design.
(3) The switch-over threshold is the maximum voltage differential between the VLDO and VOUT pins which ensures that VLDO will internally
switch-over to VOUT. The non-switch-over threshold is the minimum voltage differential between the VLDO and VOUT pins which ensures
that VLDO will not switch-over to VOUT.
(4) The LDO drop out voltage is the voltage at which the LDO output drops 2% below the nominal regulation point.
