AME8806_08 Datasheet, PDF (1/18 Pages) Analog Microelectronics – 600mA CMOS LDO

AME
AME8806 / 8809 / 8842
n General Description
The AME8806/8809/8842 family of positive, linear regu-
lators feature low quiescent current (30µA typ.) with low
dropout voltage, making them ideal for battery applica-
tions. The space-saving SOP-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 AME8806/8809/8842 is stable with an output ca-
pacitance of 2.2µF or greater.
