Ⅰ、General Description:
The AME8817 family of positive, linear regulators feature low quiescent current (35µA typ.) with low
dropout voltage, making them ideal for battery applications.
Output voltages are set at the factory and trimmed to 1.5% accuracy.
These rugged devices have both thermal shutdown, and current fold-back to prevent device failure
under the "worst" of operating conditions.
In applications requiring a low noise, regulated supply, place a 1000pF capacitor between Bypass
and Ground.
An additional feature is a "Power Good" detector, which pulls low when the output is out of regulation.
The AME8817 is stable with an output capacitance of 4.7µF 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 (ν ,
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.
