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.
