AME8817

1.5A CMOS LDO

n General Description

n Features

The AME8817 family of positive, linear regulators fea-

ture low quiescent current (35µA typ.) with low dropout

voltage, making them ideal for battery applications.

l Very Low Dropout Voltage

l Guaranteed 1.5A Output

l Accurate to within 1.5%

l 35µA Quiescent Current Typically

l Over-Temperature Shutdown

l Current Limiting

Output voltages are set at the factory and trimmed to

1.5% accuracy.

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 Good Output

l Power-Saving Shutdown Mode

l Space-Saving DDPAK-7 Package

In applications requiring a low noise, regulated supply,

place a 1000pF capacitor between Bypass and Ground.

l Low Temperature Coefficient

An additional feature is a "Power Good" detector, which

pulls low when the output is out of regulation.

The AME8817 is stable with an output capacitance of

4.7µF or greater.

n Applications

l Instrumentation

l Portable Electronics

l Wireless Devices

l PC Peripherals

l Battery Powered Widgets
