Electrical Characteristics (continued)

NOTES:

(1)

Quiescent operating current is drawn from the OUT pin while in regulation. The quiescent operating current projected to the IN pin is

approximately I

Q

× (V

OUT

/V

IN

).

(2)

Restart occurs when the EN pin transitions from low to high while the output voltage is at or near the regulation value (3.3V). See the

application section “The Enable Pin” for details.
