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