Description
AIC1746 is optimized for low ESR ceramic capacitor operation with 150mA continuous current. It 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, 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, AIC1746s current limit and thermal protection provide protection against any overload condition that would cause excessive junction temperatures.
