AAT AAT3242
The AAT3242 is a dual low dropout linear regulator with Power OK (POK) outputs. The AAT3242 has independent input voltage and enable pins for increased design flexibility. This device features a very low quiescent current (140µA typical) and low dropout voltages (typically 200mV and 400mV at the full output current level), making it ideal for portable applications where extended battery life is critical.| Part No. | AAT3242 |

GENERAL DESCRIPTION
Two integrated regulators 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. The AAT3242 has complete over-current/short-circuit and over-temperature protection circuits to guard against extreme operating conditions. The AAT3242 is available in a space-saving, Pbfree, 12-pin TSOPJW package. This device is capable of operation over the -40°C to +85°C temperature range. AAT3242FEATURES
