AME8801 / 8812 / 8840

n General Description

n Functional Block Diagram

TheAME8801/8812/8840 family of positive, linear regu-

lators feature low quiescent current (30mA typ.) with low

dropout voltage, making them ideal for battery applica-

tions. Thespace-savingSOT-25/TSOT-25&SOT-26/TSOT-

26 packages are 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" operating conditions.

In applications requiring a low noise, regulated supply,

place a 1000 pF capacitor between Bypass and Ground.

The AME8801 is stable with an output capacitance of

2.2mF or greater.

Bypass capacitor connection.

BYP

OUT

To improve AC ripple rejection, connect a capacitor to GND.

This will also provide a soft-start function.

LDO voltage regulator output pin.

It should be decoupled with a 1µF or greater value low ESR ceramic capacitor.

AME8801 / 8812 / 8840

n Detailed Description

A third capacitor can be connected between the BY-

PASS pin and GND. This capacitor can be a low cost

Polyester Film variety between the value of 0.001 ~

0.01mF. A larger capacitor improves the AC ripple rejec-

tion, but also makes the output come up slowly. This

"Soft" turn-on is desirable in some applications to limit

turn-on surges.

The AME8801/8812/8840 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 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.

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

TheAME8801/8812/8840 switches from voltage mode

to current mode when the load exceeds the rated output

current. This prevents over-stress. TheAME8801/8812/

8840 also incorporates current foldback to reduce power

dissipation when the output is short circuited. This fea-

ture becomes active when the output drops below 0.8volts,

and reduces the current flow by 65%. Full current is re-

stored when the voltage exceeds 0.8 volts.

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 qui-

escent current is less than 1mA. This pin behaves much

like an electronic switch.

n External Capacitors

The AME8801/8812/8840 is stable with an output ca-

pacitor to ground of 2.2mF or greater. Ceramic capacitors

have the lowest ESR, and will offer the best AC perfor-

mance. Conversely, Aluminum Electrolytic capacitors

exhibit the highest ESR, resulting in the poorest AC re-

sponse. Unfortunately, large value ceramic capacitors are

comparatively expensive. One option is to parallel a 0.1mF

ceramic capacitor with a 10mFAluminum Electrolytic. The

benefit is low ESR, high capacitance, and low overall cost.

A second capacitor is recommended between the in-

put and ground to stabilize Vin. The input capacitor should

be at least 0.1mF to have a beneficial effect.
