AME8801/8812/8840

300mA CMOS LDO

n General Description

n Features

The AME8801/8840 family of positive, linear regulators

feature low quiescent current (30µA typ.) with low drop-

out voltage, making them ideal for battery applications.

The space-saving SOT-23-5 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-Saving Shutdown Mode

l Space-Saving SOT-25 (SOT-23-5) 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 AME8801 is stable with an output capacitance of

2.2µF or greater.

n Applications

l Instrumentation

l Portable Electronics

l Wireless Devices

l Cordless Phones
