The AAT3218 MicroPower low dropout linear regulatoris ideally suited for portable applications wherevery fast transient response, extended battery life,and small size are critical. The AAT3218 has beenspecifically designed for high-speed turn-on and turnoffperformance, fast transient response, and goodpower supply ripple rejection (PSRR), and is reasonably low noise, making it ideal for powering sensitivecircuits with fast switching requirements
