Description

AIC1747-25GU3TR is a low noise, low dropout linear regulator that is housed in a small SOT-23-5 package. It is in the "ON" state when the SHDN pin is set to a logic high level. With a low dropout voltage of 90mV at 50mA load current, it offers a high precision output voltage of ±2%. The device is ideal for battery power applications due to its low quiescent current and low dropout voltage. It also eliminates the need for a reverse voltage protection diode with its internal reverse bias protection. AIC1747-25GU3TR provides enhanced performance for critical applications with its high ripple rejection and low noise.
