General Description
The AME8806/8809 family of positive, linear regula-
tors feature low quiescent current (30
μ
A typ.) with low
dropout voltage, making them ideal for battery applica-
tions. The space-saving SO-8 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 AME8806/8809 is stable with an output capacitance
of 2.2
μ
F or greater.
