... General Description The AAT3242 is a dual low dropout linear regulator with Power OK (POK) outputs. Two integrated reg- ulators provide a high power 300mA output and a lower power 150mA output, making this device ideal for use with microprocessors and DSP cores in portable products. Two POK pins provide open drain output signals when their respective regulator output is within regulation ...
