Description

The AIC1730 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 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 AIC1730 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 provide enhanced performance for critical applications. The noise bypass pin can be connected an external capacitor to reduce the output noise level.
