300mA CMOS LDO
AME8803 / 8814
n General Description
n Functional Block Diagram
The AME8803/8814 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-26 package is attractive for "Pocket"
and "Hand Held" applications.

Shutdown
These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under the
"Worst" of operating conditions.
EN
BYP
Vref x110%
An additional feature is a "Power Good" detector, which
pulls low when the output is out of regulation. In applications requiring a low noise, regulated supply, place a
1000pF capacitor between Bypass and ground.

AME8803 / 8814
n Detailed Description
The AME8803/8814 family of CMOS regulators contain a PMOS pass transistor, voltage reference, error amplifier, over-current protection, thermal shutdown, and
Power Good detection circuitry.
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 300mA. During thermal shutdown,
the output voltage remains low. Normal operation is restored when the junction temperature drops below 120oC.
The AME8803/8814 switches from voltage mode to current mode when the load exceeds the rated output current. This prevents over-stress. The AME8803 also incorporates current foldback to reduce power dissipation
when the output is short circuited. This feature becomes
active when the output drops below 0.8volts, 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.
n Enable
The Enable pin normally floats high. When actively,
pulled low, the PMOS pass transistor shuts off, and all
internal circuits are powered down. In this state, the
quiescent current is less than 1µA. This pin behaves
much like an electronic switch.
n Power Good
The AME8803/8814 includes the Power Good feature.
When the output is not within +15% of the specified voltage, it pulls low. This can occur under the following conditions:
1) Input Voltage too low.
2) During Over-Temperature.
3) During Over-Current.
4) If output is pulled up.
(Note: PG pin is an open-drain output.)
n External Capacitors
The AME8803/8814 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.
A third capacitor can be connected between the BYPASS pin and GND. This capacitor can be a low cost
Polyester Film variety between the value of 0.001 ~
0.01µF. A larger capacitor improves the AC ripple rejection, but also makes the output come up slowly. This
"Soft" turn-on is desirable in some applications to limit
turn-on surges.
