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.
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.
