AME8806 / 8809 / 8842

600mA CMOS LDO

n General Description

n Features

The AME8806/8809 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 SO-8 package is attractive for

"Pocket" and "Hand Held" applications.

l Very Low Dropout Voltage

l Guaranteed 600mA 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 Noise Reduction Bypass Capacitor

l Power-Saving Shutdown Mode

l Space-Saving SO-8 Package

l Factory Pre-set Output Voltages

l Low Temperature Coefficient

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 2.2µF or greater.
