Ⅰ、General Description:
The AME8804 family of positive, linear regulators feature low ground current (35A typ.) with low
dropout voltage, making them ideal for battery applications.The space-saving SOT-26/TSOT-26 and
SOT-25/TSOT-25 packages are attractive for "Pocket" and "Hand Held" ap-plications.
These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure
under the "Worst" operating conditions.
The SOT-26/TSOT-26 version also features a "Power Good" detector, which pulls low when the output
is out of regulation.
The AME8804 is stable with an output capacitance of 2.2F or greater.

Ⅲ、Failures In Time Calculation:
Use HTOL test information mentioned in sectionⅣ, FIT (Failures In Time) can be calculated as below:
FIT  ( x 2 ( ,
CL )
 10 9 ) /( 2  S  H  AF )  ( 4 .61  10 9 ) /( 2  77  1000  280 .59 )
=106.69 (pieces per 109 hours) @ 40℃ with 90% Confidence Level.
Where AF is acceleration factor setting activation energy to 1.0eV as zero failure.
