AME8805 / 8813
n General Description
n Functional Block Diagram
TheAME8805/8813 family of positive, linear regulators
feature low quiescent current (30mA typ.) with low drop-
out voltage, making them ideal for battery applications.
The space-saving SOT-89, SOT-223 and SOT-23 pack-
ages are attractive for "Pocket" and "Hand Held" applica-
tions.

600mA CMOS LDO
n Detailed Description
n External Capacitors
The AME8805/8813 family of CMOS regulators con-
tain a PMOS pass transistor, voltage reference, error am-
plifier, over-current protection, and thermal shutdown.
The AME8805/8813 is stable with an output capacitor
to ground of 2.2mF 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. Un-
fortunately, large value ceramic capacitors are compara-
tively expensive. One option is to parallel a 0.1mF ce-
ramic capacitor with a 10mF Aluminum Electrolytic. The
benefit is low ESR, high capacitance, and low overall cost.
The P-channel pass transistor receives data from the
error amplifier, over-current shutdown, and thermal pro-
tection circuits. During normal operation, the error ampli-
fier compares the output voltage to a precision reference.
Over-current and Thermal shutdown circuits become ac-
tive when the junction temperature exceeds 150oC, or
the current exceeds 600mA. During thermal shutdown,
the output voltage remains low. Normal operation is re-
stored when the junction temperature drops below 120oC.
A second capacitor is recommended between the in-
put and ground to stabilize Vin. The input capacitor should
be at least 0.1mF to have a beneficial effect.
TheAME8805/8813 switches from voltage mode to cur-
rent mode when the load exceeds the rated output cur-
rent. This prevents over-stress. The AME8805/8813 also
incorporates current foldback to reduce power dissipa-
tion when the output is short circuited. This feature be-
comes active when the output drops below 0.8 volts, and
reduces the current flow by 65%. Full current is restored
when the voltage exceeds 0.8 volts.
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.
