DESCRIPTION

AIC1742 is a low noise, low dropout linear

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

package. The device is in the “ON” state when

the SHDN pin is set to logic high level. A low

dropout voltage of 90mV at 50mA load current

is performed. 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 AIC1742 provide enhanced

performance for critical applications. The

noise bypass pin can be connected an

external capacitor to reduce the output noise

level.
