PIN DESCRIPITON

Power is supplied to the device through this pin and requires an input filter capacitor. In general, an

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

The output supplies power to loads. The output capacitor is required to provide a stable output voltage.

The APE8865-HF-3 is stable with an output capacitor of 1µF or greater. A larger output capacitor will

be required for applications with large transient loads to limit peak voltage transients, and can also

reduceoutput noise, improve stability and PSRR.

Application Description

The APE8865-3 series are low dropout linear
regulators that can provide 300mA output current
with a drop-out voltage of about 300mV. Also, current
li

mit and on-chip thermal shutdown features provide

p

rotection against any combination of overload or

junction te

mperature.

1.Output and Input Capacitor

The APE8865-3 regulator is designed to be stable
with a wide range of output capacitors. The ESR of
the output capacitor affects stability. Larger values
of the output capacitor decrease the peak deviations
and provide
current changes.
The various capacitor types (aluminum, ceramic,
tantalum) have different characteristics such as
temperature and voltage coefficients. All ceramic
capacitors are manufactured with a variety of
dielectrics, each with different behavior across
temperature and app lications. Com mon dielectric s
used are X5R, X7R and Y5V. It is recommended
to use 1uF X5R or X7R dielectric ceramic capacitors
with 30mΩ to 50mΩ ESR range between device
outputs to ground for transient stability.
The APE8865-3 is designed to be stable with low
ESR ceramic capacitors, and higher values of
capacitors and ESR can improve output stability.

mperature that exceeds the shutdown

improved transient response for larger

APE8865-HF-3

So the ESR of the output capacitor is very important
because it generates a zero to provide phase
lead for loop stability.

There are no requirem ents for the ESR on the
input capacitor, but its voltage and temperature
coefficient have to be considered for the device
application environment.

2.Protection Features
In order to prevent overloading or a thermal

ition from damaging the device, the APE8865-3

cond

regulator has internal thermal and current-limiting
functions designed to protect the device.

rapidly shut off the internal P-channel

will
MOSFET pass element during overloading
or an over-temperature condition.

3.Thermal Consideration
The power handling capability of the device is
limited by the maximum operation junction

temperature (125°C). The power dissipated by
the device can be estimated by PD = IOUT ×

(VIN-VOUT). This power dissipation must be
lower than the maximum power dissipation
listed in the “Absolute Maximum Ratings” section.
