[Note 4] Specifications over the -40°C to +85°C operation ambient temperature are guaranteed by design, characterization and statistical correlation.

[Note 6] Guaranteed by design, not 100% production tested.

[Note 8] Minimum input voltage is measured when output voltage is reduced by 2% as compared to the nominal condition under full load. Dropout is

calculated as VIN(MIN)/2 - VCORE.
