The AME1300 combines a Low Dropout Regulator and
a Microprocessor Reset Monitor in a space-saving 8-Pin
MSOP package. Total supply current is 50µA(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 cur-
rent is reduced to 10µA(typical). The AME1300 is stable
with an output capacitor of only 2.2µF and has a mini-
mum 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 (10µsec typically) when
released from shutdown.
