The AAT3238 MicroPower low dropout (LDO) linear regulatoris ideally suited for portable applications whervery fast transient response, extended battery life, andsmall size are critical. The AAT3238 has been specificallydesigned for high-speed turn-on and turn-off performance,fast transient response, good power supply ripplerejection (PSRR), and is reasonably low noise, makingit ideal for powering sensitive circuits with fastswitching requirements.
