REL-AME8815-Cu-A
General Description:
The AME8815 family of linear regulators feature low quiescent current (45mA typ.) with low dropout
voltage, making them ideal for battery applications. It is available in TO-252 and TO-220 packages. The
space-efficient SOT-223 and TO-263 packages are attractive for "Pocket" and "Hand Held" 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.
The AME8815 is stable with an output capacitance of 4.7
F or greater.

Failures In Time Calculation:
Use HTOL test information mentioned in section , 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.
