n General Description

nn

The AME8805/8810 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 and SOT-223 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" of operating conditions.

The AME8805/8810 is stable with an output capacitance
of 2.2µF or greater .

n Detailed Description

nn

The AME8805/8810 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 600mA. During thermal
shutdown, the output voltage remains low. Normal op­eration is restored when the junction temperature drops
below 120oC.

The AME8805/8810 switches from voltage mode to cur­rent mode when the load exceeds the rated output cur­rent. This prevents over-stress. The AME8805/8810
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.

n External Capacitors

nn

The AME8805/8810 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.

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.
