8. Deviation from nominal. For adjustable versions, Pin ADJ connected to V out .
9. See Typical Characteristics section for additional information.
10. V DO is constrained by the minimum input voltage of 2.5 V.
11. V out is set by external resistor divider to 5 V.
12. V n for other fixed voltage versions, as well as adjustable versions set to other output voltages, can be calculated from the following formula:
V n = V n(x) * V out / 1.25, where V n(x) is the typical value from the table above.
13. Performance guaranteed over specified operating conditions by design, guard banded test limits, and/or characterization, production 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.
14. Values are based on design and/or characterization.
