General Description
The AME1300 combines a Low Dropout Regulator and
a Microprocessor Reset Monitor in a space-saving MSOP-
8 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, RESETB output remains valid and supply
current is reduced to 10µA(typical). The AME1300 is
stable with an output capacitor of only 2.2µF 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 (10µsec typically) when re-
leased from shutdown.
