AME1300
300mA CMOS LDO with RESET Function
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 10
μ
A. This
pin behaves much like an electronic switch.
RESET Output
The RESET output is driven active low within 40
μ
sec of
V
falling through the reset threshold.RESET is main-
tained active for a minimum of 140msec after V
rises
above the reset threshold. The AME1300 has an active-
low RESET output. The output of the AME1300 is guar-
anteed vaild down to V
= 1V and is optimized to reject
fast transient glitches on the V
DET
line.
The AME1300 is stable with an output capacitor to
ground of 2.2
μ
F or greater. Ceramic capacitors have the
lowest ESR, and will offer the best AC performance. Con-
versely, Aluminum Electrolytic capacitors exhibit the high-
est ESR, resulting in the poorest AC response. Unfortu-
nately, large value ceramic capacitors are comparatively
expensive. One option is to parallel a 0.1
μ
F ceramic
capacitor with a 10
μ
F Aluminum Electrolytic. The benefit
is low ESR, high capacitance, and low overall cost.
A second capacitor is recommended between the in-
put and ground to stabilize Vin. The input capacitor should
be at least 0.1
μ
F to have a beneficial effect.
A third capacitor can be connected between the BY-
PASS pin and GND. This capacitor can be a low cost
Polyester Film variety between the value of 0.001~0.01
μ
F.
A larger capacitor improves the AC ripple re-jection,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.
