Note 1:
Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2:
Start-up testing is done with a 100k
equivalent load on V
OUT
.
Note 3:
Currents flowing into the device are positive polarity. Currents
flowing out of the device are negative polarity.
Note 4:
Commercial grade specifications are guaranteed over the 0
°
C to
70
°
C operating temperature range. In addition, commercial grade
specifications are assured over the –40
°
C to 85
°
C operating temperature
range by design, characterization and correlation with statistical process
controls. Industrial grade specifications are guaranteed and tested over the
–40
