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 TJ = TA = 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 Vin = 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.
