AIC1731

300mA, Low Dropout Linear Regulator

with Shutdown

FEATURES

DESCRIPTION

z Active Low Shutdown Control.

AIC1731 is a 300mA low noise, low dropout

z Very Low Quiescent Current.

linear regulator, and is housed in small SOT-23-5

z Very Low Dropout Voltage of 470mV at 300mA

Output Current (3.0V Output Version)

z 1.3V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V Output

Voltage.

and SOT-89-5 package. The device is in the “ON”

state when the SHDN pin is set to logic high

level. An internal P-MOSFET pass transistor is

used to achieve 470mV low dropout voltage at

300mA load current. It offers high precision

z Short Circuit and Thermal Protection.

z ±2% Output Tolerance.

z Miniature Package: SOT-23-5 and SOT-89-5

output voltage of ±2%. The quality of low

quiescent current and low dropout voltage makes

this device ideal for battery power applications.

The internal reverse bias protection eliminates

the requirement for a reverse voltage protection

diode. The high ripple rejection and low noise of

AIC1731 provide enhanced performance for

critical applications. The noise bypass pin can be

connected an external capacitor to reduce the

output noise level.

APPLICATIONS

z PDA

z DSC

z Notebook

z Pagers

z Personal Communication Equipment

z Cordless Telephones

z Portable Instrumentation

z Portable Consumer Equipment
