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. The
noise bypass pin can be connected an
external capacitor to reduce the output noise
level.
