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 dropout voltage makes this device ideal
for battery power applications. The high ripple
rejection and low noise of the AIC1189 provide
enhanced performances for critical applications
such as cellular phones, and PDAs.
In addition, a logic-level shutdown input is
included, which reduce supply current to 0.01µA
(typ.) in shutdown mode with fast turn-on time
less than 100µs. The AIC1189’s current limit and
thermal protection provide protection against any
overload condition that would create excessive
junction temperatures.
