AME1300

The AME1300 combines a Low Dropout Regulator and a Microprocessor Reset Monitor in a space-saving 8-Pin MSOP package. Total supply current is 50mA(typical),20 to 60 times lower than in bipolar regulators .

The AME1300 has an extremely precise output with a typical accuracy of ±1.5%. Other key features include ultra low noise operation, very low dropout voltage and internal feed-forward compensation for fast response to step changes in load. The AME1300 incorporates both over-temperature and over-current protection. When the shutdown control EN is low, the regulator output voltage falls to zero,RESET output remains valid and supply current is reduced to 10mA(typical). The AME1300 is stable with an output capacitor of only 2.2mF and has a minimum output current of 300 mA.

An active low RESET is asserted when the detected voltage ( V_DET) falls below the reset voltage threshold. The reset output remains low for 300msec(typical) after V_DET rises above reset threshold. The AME1300 also has a fast wake up response time (10msec typically) when released from shutdown.
