The AME8815 family of linear regulators feature low
quiescent current (45µA typ.) with low dropout voltage,
making them ideal for battery applications. It is available
in D2PAK and TO-220 packages. The space-efficient
SOT-223 and DP AK package are attractive for "Pocket"
and "Hand Held" applications.
Output voltages are set at the factory and trimmed to
1.5% accuracy.
These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under
the "Worst" of operating conditions.
The AME8815 is stable with an output capacitance of
4.7µF or greater .

n Detailed Description
nn
The AME8815 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 2.2A. During thermal shutdown, the output voltage remains low. Normal operation
is restored when the junction temperature drops below
120oC.
The AME8815 behaves like a current source when the
load reaches 2.2A. However, if the load impedance
drops below 0.3 ohms, the current drops back to 600mA
to prevent excessive power dissipation. Normal operation is restored when the load resistance exceeds
0.75 ohms.
1.5A CMOS LDO
nn
n External Capacitors
nn
The AME8815 is stable with an output capacitor to
ground of 4.7µF 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.
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.
