AME
300mA CMOS LDO
AME8801 / 8812 / 8840
n General Description
n Functional Block Diagram
The AME8801/8812/8840 family of positive, linear regulators feature low quiescent current (30µA typ.) with low
dropout voltage, making them ideal for battery applications. The space-saving SOT-25/TSOT-25 & SOT-26/TSOT26 packages are attractive for "Pocket" and "Hand Held"
applications.
These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under the
"Worst" operating conditions.

In applications requiring a low noise, regulated supply,
place a 1000 pF capacitor between Bypass and Ground.
The AME8801 is stable with an output capacitance of
2.2µF or greater.

Pin Description
Input voltage pin.
It should be decoupled with 1µF or greater capacitor.
Ground connection pin.
Enable pin.
When pulled low, the PMOS pass transistor turns off, current consuming less
than 1µA.
BYP
Bypass capacitor connection.
To improve AC ripple rejection, connect a capacitor to GND.
This will also provide a soft-start function.
OUT
LDO voltage regulator output pin.
It should be decoupled with a 1µF or greater value low ESR ceramic capacitor.

AME8801 / 8812 / 8840
n Detailed Description
The AME8801/8812/8840 family of CMOS regulators
contain a PMOS pass transistor, voltage reference, error
amplifier, over-current protection, and thermal shutdown.
The P-channel pass transistor receives data from the
error amplifier, over-current shutdown, and thermal protection circuits. During normal operation, the error amplifier compares the output voltage to a precision reference.
Over-current and Thermal shutdown circuits become active when the junction temperature exceeds 150oC, or
the current exceeds 300mA. During thermal shutdown,
the output voltage remains low. Normal operation is restored when the junction temperature drops below 120oC.
The AME8801/8812/8840 switches from voltage mode
to current mode when the load exceeds the rated output
current. This prevents over-stress. The AME8801/8812/
8840 also incorporates current foldback to reduce power
dissipation when the output is short circuited. This feature becomes active when the output drops below 0.8volts,
and reduces the current flow by 65%. Full current is restored when the voltage exceeds 0.8 volts.
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 up 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.
n Enable
The Enable pin normally floats high. 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 1µA. This pin behaves much
like an electronic switch.
n External Capacitors
The AME8801/8812/8840 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.
