(1)

The minimum IN operating voltage is 2.7 V or VO(typ) + 1 V, whichever is greater. The maximum IN voltage is 10 V.

(2)

If VO ≤ 1.8 V then VI(min) = 2.7 V, VI(max) = 10 V:

If VO ≥ 2.5 V, then VI(min) = VO + 1 V, and VI(max) = 10 V:

(3)

IN voltage equals VO(typ) – 100 mV; adjustable output voltage set to 3.3 V nominal with external resistor divider. Dropout voltage of 1.8 V

and 2.5 V is limited by input voltage-range limitations.
