nGeneral Description
nApplications
The AME8831 family of positive, linear regulators fea-
ture low quiescent current (17mA typ.) with low dropout
voltage, making them ideal for battery applications. The
space-saving SOT-25 package is attractive for “Pocket”
l Instrumentation

l PC Peripherals
and “Hand Held”applications.
These rugged devices have both Thermal Shutdown,
and Current limitation to prevent device failure under the
“Worst” of operating conditions. In applications requires
a low noise regulated supply. The AME8831 family uses
the SR pin to program the output voltage’ s slew rate to
control the in-rush current. This is specifically used in
the USB application where large load capacitance is

nDetail Description
The AME8831 family of CMOS regulators contain a
PMOS pass transistor, voltage reference, error ampli-
fier, over-current protection, and thermal shutdown func-
tion.
The P-channel pass transistor receives data from
the error amplifier, over-current limit, and thermal pro-
tection 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 about 350mA. During
thermal shutdown, the output voltage remains low.
Normal operation is restored when the junction tem-
perature drops below 120oC.
The AME8831 switches from voltage mode to cur-
rent mode when the load exceeds the rated output
current. This prevents over-stress.
nExternal Capacitors
The AME8831 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.
Unfortunately, large value ceramic capacitors are com-
paratively expensive. One option is to parallel a 0.1mF
ceramic capacitor with a 10mF 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 0.1mF 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
nEnable
The Enable pin is optional. EN for active high en-
able, EN for active low enable. When disable the En-
able Pin EN=0, EN=VIN, the PMOS pass transistor
shuts off, and all internal circuits are powered down.
In this state, the standby current is less than 1mA.
