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.
