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 MSOP8 package. Total supply current is 50µA (typical), 20 to
60 times lower than in bipolar regulators .
l Instrumentation
The AME1300 has an extremely precise output with a
l PC Peripherals
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

reset output remains low for 300msec(typical) after VDET
rises above reset threshold. The AME1300 also has a
fast wake up response time (10µsec typically) when released from shutdown.

n Detailed Description
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,VOUT remains stable
and within regulation at very low load currents(an important consideration in RTC and CMOS RAM battery backup applications) as well as with any type of capacitor (see
below). AME1300 pin functions are detailed below:

Pin Description
RESETB output remains low while VDET is below the reset voltage
threshold, and for 300msec VDET rises above reset theshold.

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, RESETB output remains valid and supply
current is reduced to 10µA (typ.)

n Enable
When actively pulled low, the PMOS pass transistor
shuts off, and all internal circuits are powered down. In
this state, the quiescent current is less than 10µA. This
pin behaves much like an electronic switch.
RESETB Output
The RESETB output is driven active low within 40µsec
of VDET falling through the reset threshold.RESETB is
maintained active for a minimum of 140msec after VDET
rises above the reset threshold. The AME1300 has an
active-low RESETB output. The output of the AME1300
is guaranteed vaild down to V DET = 1V and is optimized to
reject fast transient glitches on the VDET line.
n External Capacitors
The AME1300 is stable with an output capacitor to
ground of 2.2µF or greater. Ceramic capacitors have the
lowest ESR, and will offer the best AC performance. Conversely, Aluminum Electrolytic capacitors exhibit the highest ESR, resulting in the poorest AC response. Unfortunately, large value ceramic capacitors are comparatively
expensive. One option is to parallel a 0.1µF ceramic capacitor with a 10µF Aluminum Electrolytic. The benefit is
low ESR, high capacitance, and low overall cost.
A second capacitor is recommended between the input and ground to stabilize Vin. The input capacitor should
be at least 0.1µF to have a beneficial effect.
A third capacitor can be connected between the BYPASS pin and GND. This capacitor can be a low cost
Polyester Film variety between the value of 0.001~0.01µF.
A larger capacitor improves the AC ripple rejection,but
also makes the output come slowly. This“ Soft” turn-on
is desirable in some applications to limit turn-on surges.
All capacitors should be placed in close proximity to
the pins. A “ Quiet” ground termination is desirable. This
can be achieved with a “ Star” connection.
