Note 1:
Absolute Maximum Ratings are those values beyond which the life
Note 3:
Current consumed by Disconnect PNP when there is no load on of a device may be impaired. the OUT pin.
Note 2:
The LT3464E is guaranteed to meet performance specifications
Note 4:
This figure is computed according to ((VFB falling + VFB rising)/2) from 0°C to 70°C. Specifications over the –40°C to 85°C operating –VCONTROL. temperature range are assured by design, characterization and correlation with statistical process controls. 3464f 2
