AME8803/8814

300mA CMOS LDO

n General Description

n Features

The AME8803 family of positive, linear regulators fea-

ture low quiescent current (30µA typ.) with low dropout

voltage, making them ideal for battery applications. The

space-saving SOT-23-6 package is attractive for

"Pocket" and "Hand Held" applications.

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 Noise Reduction Bypass Capacitor

l Power Good Detector

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

pulls low when the output is out of regulation. In appli-

cations requiring a low noise, regulated supply, place a

1000pF capacitor between Bypass and ground.

l Power-Saving Shutdown Mode

l Space-Saving SOT-26 (SOT-23-6)

l Factory Pre-set Output Voltages

l Low Temperature Coefficient

The AME8803 is stable with an output capacitance of

2.2µF or greater.

n Applications

l Instrumentation

l Portable Electronics

l Wireless Devices

l Cordless Phones

l PC Peripherals

n Functional Block Diagram

l Battery Powered Widgets
