6. Deviation from nominal. For adjustable versions, Pin ADJ connected to OUT.
7. Use pulse loading to limit power dissipation (duration < 100 mS and duty cycle < 1%).
8. V_DO = V_IN − V_OUT. For <2.5 V versions, V_DO will be constrained by the minimum input voltage of 2.5 V.
9. V_DO = V_IN − V_OUT. For output voltage set to <2.5 V, V_DO will be constrained by the minimum input voltage.
10. 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) / 1.25, where V_n(x) is the typical value from the table above.
11. Not tested in production. Limits are guaranteed by design.
