FUNCTIONAL PIN DESCRIPTION
Pin Name
Pin Function
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.
VIN
The output supplies power to loads. The output capacitor is required to prevent output voltage unstable. The
APE8805 is stable with an output capacitor 1µF or greater. The larger output capacitor will be required for
application with large transit load to limit peak voltage transits, besides could reduce output noise, improve
stability, PSRR.

APPLICATION INFORMATION
The APE8805 series are low dropout linear regulators
that could provide 600mA output current at dropout
voltage about 600mV. Besides, current limit and on
chip thermal shutdown features provide protection
against any combination of overload or ambient
temperature that could exceed junction temperature.
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.
1.OUTPUT AND INPUT CAPACITOR
2.PROTECTION FEATURES
The APE8805 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 provides to improve
transition response for larger current changes.
The capacitor types (aluminum, ceramic, and
tantalum) 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 50m Ω ESR range betw- een device outputs
to ground for transient stability. The APE8805
is designed to be stable with low ESR ceramic
capacitors and higher values of capacitors and
ESR could improve output stability. So the
In order to prevent overloading or thermal condition
from damaging device, APE8805 regulator has
internal thermal and current limiting functions
designed to protect the device. It will rapidly shut
off PMOS pass element during overloading or
over temperature condition.
3.THERMAL CONSIDERATION
The power handling capability of the device will
be limited by maximum operation junction
temperature (125°C). The power dissipated by the
device will be estimated by
PD = IOUT x (VIN-VOUT).
The power dissipation should be lower than the
maximum power dissipation listed in
“Absolute Maximum Ratings” section.
