DESCRIPTION

The APE8805A is a low dropout, positive linear regu-

lator with very low quiescent current. The APE8805A

can supply 600mA output current with low dropout

voltage at about 600mV. The BP pin with a 10nF

bypass capacitor can help reduce the output noise

level. The shutdown function can provide remote

control for the external signal to decide the on/off

state of APE8805A. With a logic high level at SHDN

pin, the device is in the on state, and vice versa.

The APE8805A regulator is able to operate with output

capacitors as small as 1µF for stability. Other than

the current limit protection, APE8805A also offers the

on chip thermal shutdown feature providing protection

against overload or any condition when the ambient

temperature exceeds the maximum junction tempe-

rature.

The APE8805A offers high precision output voltage of

± 2%. It is available in fixed output voltages including

1.5V, 1.8V, 2.0V, 2.5V, 2.8V, 3.0V, and 3.3V.

The APE8805A is housed in low-profile, space-saving

5-lead SOT-23 package.

FUNCTIONAL PIN DESCRIPTION

Pin Name Pin Function

VIN Power is supplied to this device from this pin which is required an input filter capacitor. In general, the input

capacitor in the range of 1µF to 10µF is sufficient.

VOUT

The output supplies power to loads. The output capacitor is required to prevent output voltage from oscillation.

The APE8805A is stable with an output capacitor 1µF or greater. The larger output capacitor will be required for

application with larger load transients. The large output capacitor could reduce output noise, improve stability,

and PSRR.

APPLICATION INFORMATION

The APE8805A is a low dropout linear regulator that

could provide 600mA output current at dropout volt-

age about 600mV. Current limit and on chip thermal

shutdown features provide protection against any

combination of overload or ambient temperature that

could exceed maximum junction temperature.

1. Output and Input Capacitor

The APE8805A regulator is designed to be stable

with a wide range of output capacitors. The ESR

of the output capacitor affects stability. Larger

value of the output capacitor decreases the peak

deviations and improves transient response for

larger current changes.

The capacitor types (aluminum, ceramic, and tant-

alum) have different characterizations such as

temperature and voltage coefficients. All ceramic

capacitors are manufactured with a variety of

dielectrics, each with different behavior across

temperature and applications. Common dielectrics

used are X5R, X7R and Y5V. It is recommended

to use 1uF to 10uF X5R or X7R dielectric ceramic

capacitors with 30mΩ to 50mΩ ESR range betw-

een device outputs and ground for stability. The

APE8805A is designed to be stable with low ESR

ceramic capacitors and higher values of ca-

pacitors and ESR could improve output stability.

The ESR of output capacitor is very important

because it generates a zero to provide phase lead

for loop stability.

There are no requirements for the ESR on the

input capacitor, but its voltage and temperature

coefficient have to be considered for device

application environment.

2. Protection Features

In order to prevent overloading or thermal con-

dition from damaging the device, APE8805A has

internal thermal and current limiting functions

designed to protect the device. It will rapidly

shut off PMOS pass element during overload-

ing or over temperature condition.

3. Thermal Consideration

The power handling capability of the device will

be limited by maximum operation junction

temperature. The power dissipated by the

device will be estimated by PD = IOUT ×

(VIN-VOUT). The power dissipation should be

lower than the maximum power dissipation

listed in “Absolute Maximum Ratings” section.

4. Shut down Operation

The APE8805A is shutdown by pulling the

SHDN

input low, and turned on by driving the

SHDN

high. If this function is not used, the

SHDN

input should be tied to VIN to keep the regu-

lator on at all times (the

SHDN

must not be

left floating).
