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.
