n DESCRIPTION
The AIC1730 is a low noise, low dropout linear
regulator, housed in a small SOT-23-5 & SOT-236W 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.
