Notes

Room = 25_C, Full = −40 to 85_C.

The algebraic convention whereby the most negative value is a minimum and the most positive a maximum.

Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

Timing is measured from 90% of LDO #1’s final value to 90% of LDO #2’s final value.

Guaranteed by design.

For higher output of the regulator pair.

Dropout voltage is defined as the input to output differential voltage at which the output voltage drops 2% below the output voltage measured with a 1-V

differential, provided that VIN does not drop below 2.25 V. When VOUT(nom) is less than 2.25 V, the output will be in regulation when 2.25 V − VOUT(nom) is

greater than the dropout voltage specified.
