Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product

performance may not be indicated by the Electrical Characteristics if operated under different conditions.

8. Performance guaranteed over the indicated operating temperature range by design and/or characterization tested at TA [ TJ. Low duty

cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as possible.

9. Minimum input voltage Vin_min is 4.4 V or (Vout_nom1,2 + 1 V) whichever is higher. Vout_nom1,2 measured at ADJ1,2 pin due to excluding

Rn1 and Rn2 accuracy.

10. Measured when the output voltage Vout1,2 has dropped by 2% of Vout_nom1,2 from the nominal valued obtained at Vin = Vout1,2 + 8.5 V.

11. Values based on design and/or characterization.

12. Not guaranteed in dropout.
