† Notice: Stresses above those listed under “Maximum

Ratings” may cause permanent damage to the device.

This is a stress rating only and functional operation of

the device at those or any other conditions above those

indicated

in

the

operational

sections

of

this

specification is not intended. Exposure to maximum

rating conditions for extended periods may affect

device reliability.

Note 1:

The input voltage should be > output voltage + headroom voltage; higher load currents increase the input voltage

necessary for regulation. See characterization graphs for typical input to output operating voltage range.
