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
FP6136 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 FP6136 series are low dropout linear regulators
that could provide 1A output current at dropout
voltage about 1.1V. Besides, current limit and on
chip thermal shutdown features provide protection
against overload or any condition when the ambient
temperature exceeds the junction temperature.
Protection Features
In order to prevent overloading or thermal condition
from damaging device, FP6136 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.
Output and Input Capacitor
Thermal Consideration
The FP6136 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 transition response for larger current
changes.
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.
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 30mΩ to 50mΩ ESR range between
device outputs to ground for transient stability. The
FP6136 is designed to be stable with low ESR
ceramic capacitors and higher values of capacitors,
and ESR could improve output stability. 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.
