 ^DESCRIPTION
A low noise, high PSRR and ultra low dropout
linear regulator AIC1190 is optimized for low ESR
ceramic capacitors operation with 1A continuous
current.
The AIC1190 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 1A 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 AIC1190 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 less than
0.1µA (typ.) in shutdown mode with fast turn-on
time less than 100µs. The AIC1190’s current limit
and thermal protection provide protection against
any overload condition that would create
excessive junction temperatures.
