10. Refer to ABSOLUTE MAXIMUM RATINGS and APPLICATION INFORMATION for Safe Operating Area.
11. Performance guaranteed over the indicated operating temperature range by design and/or characterization tested at T A [ T J . Low duty
cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as possible.
12. Measured when output voltage falls 100 mV below the regulated voltage at V in = 13.2 V. If V out < 5 V, then V DO = V in – V out . Maximum dro-
pout voltage value is limited by minimum input voltage V in = 4.5 V recommended for guaranteed operation at maximum output current.
13. Values based on design and/or characterization.
14. Recommended for typical trigger time. T WD = t CW + 1/2 * t OW
