DESCRIPTION

AIC1731 is a 300mA low noise, low dropout

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

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 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.
