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
FP6132 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 FP6132 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.
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
The FP6132 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.
Protection Features
In order to prevent overloading or thermal condition
from damaging device, FP6132 regulator has
internal thermal and current limiting functions
designed to protect the device. It will rapidly shut
off PMOS pass element during over temperature
condition.
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 1μF to 10μF X5R or X7R dielectric ceramic
capacitors with 30m to 50m ESR range between
device outputs to ground for transient stability. The
FP6132 is designed to be stable with low ESR
ceramic capacitors and higher values of capacitors
and ESR could improve output stability.
Thermal Consideration
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.
