300mA CMOS LDO with RESET Function

AME1300

n General Description

n Applications

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 .

l PC Peripherals

The AME1300 has an extremely precise output with a

typical accuracy of ±1.5%. Other key features include

l Battery Powered Widgets

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.

V_IN

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_DETrises above reset threshold. The AME1300 also has

a fast wake up response time (10µsec typically) when

released from shutdown.
