The AAT3242 is a dual low dropout linear regulator withPower OK (POK) outputs. Two integrated regulators providea high power 300mA output and a lower power150mA output, making this device ideal for use withmicroprocessors and DSP cores in portable products.Two POK pins provide open drain output signals whentheir respective regulator output is within regulation.The AAT3242 has independent input voltage and enablepins for increased design flexibility. This device featuresa very low quiescent current (140μA typical) and lowdropout voltages (typically 200mV and 400mV at the fulloutput current level), making it ideal for portable applicationswhere extended battery life is critical. TheAAT3242 has complete over-current/short-circuit andover-temperature protection circuits to guard againstextreme operating conditions.
