Pin #
Pin Name
Pin Description
1
RESET
RESET output remains low while V
DET
is below the reset voltage
threshold, and for 300msec V
DET
rises above reset theshold.
2
V
OUT
Regulated Voltage Output.
3
GND
Ground Terminal.
4
Bypass
Reference Bypass Input. Connecting a 1000pF to this input further
reduces output noise.
5
EN
Shutdown Control Input. The regulator is fully enabled when a logic
high is applied to this input. The regulator enters shutdown when a
logic low is applied to this input. During shutdown, regulator output
voltage falls to zero, RESET output remains valid and supply current
is reduced to 10

IN
Power Supply Input.
8

DET
Detected input Voltage. V
DET
and V
OUT
can be connected together.

The AME1300 is a combination of a fixed output, low
drop-out regulator and microprocessor monitor. Unlike
bipolar regulators, the AME1300 supply current does not
increase with load current. In addition,V
remains stable
and
within regulation at very low load currents(an impor-
tant consideration in RTC and CMOS RAM battery back-
up applications) as well as with any type of capacitor
(see below). AME1300 pin functions are detailed below:
