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. Output and Input Capacitor 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 curren t 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 1 µF to 10 µF X5R or X7R dielectric ceramic capacitors with 30m Ω 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 o f 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. Protection Features In order to prevent overloading or thermal condition from damaging device, FP 6136 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 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 PD = IOUT  (VIN-VOUT). The power dissipation should be lower than the maximum power dissipation listed in “Absolute Maximum Ratings” section.
