AME, Inc.
AME8800 / 8811
300mA CMOS LDO
n General Description
n Features
The AME8800/8811 family of positive, linear regula-
tors feature low quiescent current (30µA typ.) with low
dropout voltage, making them ideal for battery applica-
tions. The space-saving SOT-23, SOT-25, SOT-89 and
TO-92 packages are attractive for "Pocket" and "Hand
Held" aplications.
l Very Low Dropout Voltage
l Guaranteed 300mA Output
l Accurate to within 1.5%
l 30µA Quiescent Current
l Over-Temperature Shutdown
l Current Limiting
These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under
the "Worst" of operating conditions.
l Short Circuit Current Fold-back
l Space-Saving SOT-23, SOT-25, SOT-89 and
TO-92 Package
The AME8800/8811 is stable with an output capacitance
of 2.2µF or greater.
l Factory Pre-set Output Voltages
l Low Temperature Coefficient
