7. Refer to ABSOLUTE MAXIMUM RATINGS and APPLICATION INFORMATION for Safe Operating Area.
8. Performance guaranteed over the indicated operating temperature range by design and/or characterization tested at T
J
= T
A
= 25°C. Low
duty cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as possible.
9. Maximum dropout voltage is limited to minimum input voltage V
in
= 1.7 V recommended for guaranteed operation at maximum output
current.
10.Refer to application information section.
11. Values based on design and/or characterization.
