AME8841_06 Datasheet, PDF (1/14 Pages) Analog Microelectronics – 600mA CMOS LDO

AME, Inc.
AME8841
n General Description
The AME8841 linear regulator features low quiescent
current (30µA typ.) with low dropout voltage, making it
ideal for battery applications. The space-saving SO-8
package is attractive for "Pocket? and "Hand Held" appli-
cations.
These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under the
"Worst" of operating conditions.
The AME8841 is stable with an output capacitance of
2.2µF or greater.
