The output supplies power to loads. The output capacitor is required to prevent output voltage from

oscillation. The FP6134 is stable with an output capacitor which is 1µF or greater. The larger output

capacitor will be required for application with larger load transients. The large output capacitor could

reduce output noise, improve stability and PSRR.

Application Information

Protection Features

The FP6134 is a low dropout linear regulator that

could provide 600mA output current at dropout

voltage about 600mV. Current limit and on chip

thermal shutdown features provide protection

against overload or any condition when the ambient

temperature exceeds the maximum junction

temperature.

In order to prevent overloading or thermal condition

from damaging the device, FP6134 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

Output and Input Capacitor

The power handling capability of the device will be

limited by allowable operation junction temperature

(125C). The power dissipated by the device will

be estimated by P_D= I_OUT (V_IN-V_OUT). The power

dissipation should be lower than the maximum

powerꢃ dissipationꢃ listedꢃ inꢃ “Absoluteꢃ Maximumꢃ

Ratings”ꢃsection.

The FP6134 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 transient 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 1µF to 10µF X5R or X7R dielectric ceramic

capacitors with 30mΩ to 50mΩ ESR range between

Shutdown Operation

The FP6134 is shutdown by pulling the ꢀꢁꢂ

input low and turned on by driving the ꢀꢁꢂ high.

If this function is not used, the ꢀꢁꢂ input should

be tied to VIN to keep the regulator on all the time

(the ꢀꢁꢂ must not be left floating).

device outputs and ground for stability.

The

FP6134 is designed to be stable with low ESR

ceramic capacitors and higher values of capacitors,

and ESR could improve output stability. 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.
