NOTES:

5. Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below the value measured

with

a

1-V

differential.

Dropout

limits

may

not

apply

because

VIN must be the greater of a) 2.2 V, or

b) VOUT(nom) + dropout voltage (Max) in order to maintain output regulation.

6. The ON/OFF input must be properly driven for reliable operation (see Application Information).
