n General Description
n Functional Block Diagram
The AME8805/8813 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-89, SOT-223 and SOT-23 packages are attractive for "Pocket" and "Hand Held" applications.

AME8805 / 8813
600mA CMOS LDO
n Detailed Description
n External Capacitors
The AME8805/8813 family of CMOS regulators contain a PMOS pass transistor, voltage reference, error amplifier, over-current protection, and thermal shutdown.
The AME8805/8813 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.
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 600mA. During thermal shutdown,
the output voltage remains low. Normal operation is restored when the junction temperature drops below 120oC.
The AME8805/8813 switches from voltage mode to current mode when the load exceeds the rated output current. This prevents over-stress. The AME8805/8813 also
incorporates current foldback to reduce power dissipation when the output is short circuited. This feature becomes 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.
10
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.
