The AIC1730 is a low noise, low dropout linear regulator, housed in a small SOT-23-5 & SOT-23- 6W package. The device is in the “ON” state

when the SHDN pin is set to a logic high level. An internal P-MOSFET pass transistor is used to achieve a low dropout voltage of 90mV at 50mA load current. It offers high precision output voltage of ±2%. The very low quiescent current and low dropout voltage make this device ideal for battery powered 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. An external capacitor can be connected to the noise bypass pin to reduce the output noise level.
