DESCRIPTION
A low noise, high PSRR and ultra low dropout linear
regulator AIC1189 is optimized for low ESR ceramic capacitors operation with 2A continuous current. The AIC1189 is designed for portable and wireless devices with demanding performance and space requirements.
The AIC1189 offers high precision output voltage of ±2% tolerance. Output voltage can also be adjusted for those other than the preset values.
A noise bypass pin is available for further reduction of output noise. The bypass pin could be floating if it’s unnecessary. At 2A load current and 2.8V output voltage, a 440mV dropout is performed. The quality of low quiescent current and low drop...
