Functional Pin Description
Pin Name
Pin Function
Power is supplied to this device from this pin which requires 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
FP6131 is stable with an output capacitor which is 1µF or greater. The larger output capacitor will be required
for application with large transit load to limit peak voltage transits. Besides, it could reduce output noise,
improve stability and PSRR.

Application Information
The FP6131 series are low dropout linear
regulators that could provide 300mA output current
at dropout voltage about 300mV. Besides, current
limit and on chip thermal shutdown features provide
protection against overload or any condition when
the ambient temperature exceeds the junction
temperature.
So 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.
Output and Input Capacitor
Protection Feature
The FP6131 regulator is designed to be stable with
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 transition response for larger current
changes.
In order to prevent overloading or thermal condition
from damaging the device, FP6131 regulator has
internal thermal and current limit functions designed
to protect the device. It will rapidly shut off PMOS
pass element during over temperature condition.
Thermal Consideration
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
The power handling capability of the device will be
limited by allowable operation junction temperature
(125C). 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.
temperature
and
applications.
Common
dielectrics used are X5R, X7R and Y5V. It is
recommended to use 1μF to 10μF X5R or X7R
dielectric ceramic capacitors with 30mΩ to 50mΩ
ESR range between device outputs to ground for
transient stability. The FP6131 is designed to be
stable with low ESR ceramic capacitors and higher
values of capacitors, and ESR could improve
output stability.
