5. Performance guaranteed over the indicated operating temperature range by design and/or characterization 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.
6. Maximum dropout voltage is limited by minimum input voltage. V IN = 1.7 V recommended for guaranteed operation at maximum output
current.
7. Refer to the Applications Information Section.
8. Values based on design and/or characterization.
9. Dropout voltage is defined as the differential voltage between V OUT and V IN , when V OUT drops 100 mV below its nominal value.
