General Description:
The AME8812 family of positive, linear regulators feature low quiescent current (30µA typ.) with low
dropout voltage, making them ideal for battery applications.
The space-saving SOT-25 package is attractive for "Pocket" and "Hand Held" applications. 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 1000 pF capacitor between Bypass
and Ground.
The AME8812 is stable with an output capacitance of 2.2µF or greater.

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