AIC1746 is optimized for low ESR ceramic
capacitor operation with 150mA continuous
current. The AIC1746 is designed for portable RF
and wireless applications with demanding
performance and space requirements.
The AIC1746 offers high precision output voltage
of ±2% tolerance. Output Voltage is available
within 1.1~4.2V. There are version of 1.1, 1.2, 1.3,
1.5, 1.8, 2.5, 2.7, 2.8, 2.85, 3.0, 3.3, 3.5, 3.7 and
3.8 for a fixed output voltage.
A noise bypass pin is available for further
reduction of output noise. At 150mA load current,
a 140mV dropout can be performed. The quality
of low quiescent current and low dropout voltage
makes the device ideal for battery power
applications. The high ripple rejection and low
noise of the AIC1746 provide enhanced
performances for critical applications such as
cellular phones, and PDAs.
In addition, AIC1746’s current limit and thermal
protection provide protection against any overload
condition that would cause excessive junction
temperatures.
