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. 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. 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 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. 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, 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. 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.
