Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired.

Note 2: Specifications over the -40°C to 85°C operating temperature range are assured by design,

characterization and correlation with statistical process controls.

Note 3: Output voltage line regulation is guaranteed by design, characterization and correlation with

statistical quality controls, not production tested.

Note 4: Bias current flows out of the NFB pin.
