AME8800 / 8811

300mA CMOS LDO

n Functional Block Diagram

n General Description

The AME8800/8811 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-23, SOT-25, SOT-89 and TO-92

packages are attractive for "Pocket" and "Hand Held" ap-

plications.

Overcurrent

Shutdown

These rugged devices have both Thermal Shutdown,

and Current Fold-back to prevent device failure under the

"Worst" of operating conditions.

n Detailed Description

The AME8800/8811 family of CMOS regulators contain

a PMOS pass transistor, voltage reference, error ampli-

fier, over-current protection, and thermal shutdown.

The AME8800/8811 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 150^oC, or

the current exceeds 300mA. During thermal shutdown,

the output voltage remains low. Normal operation is re-

stored when the junction temperature drops below 120^oC.

A second capacitor is recommended between the in-

put and ground to stabilize V_IN. The input capacitor should

be at least 0.1mF to have a beneficial effect.

The AME8800/8811 switches from voltage mode to cur-

rent mode when the load exceeds the rated output cur-

rent. This prevents over-stress. The AME8800/8811 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.
