APE8805 PIN DESCRIPTIONS PIN SYMBOL PIN DESCRIPTION VIN 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. The output supplies power to loads. The output capacitor is required to prevent output voltage unstable. The VOUT APE8805 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.

APE8805 APPLICATION INFORMATIO The APE8805 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 & Input Capacitor The APE8805 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 1uF to 10uF X5R or X7R dielectric ceramic capacitors with 30mΩ to 50mΩ ESR range betw- een device outputs to ground for transient stability. The APE8805 is designed to be stable with low ESR ceramic capacitors and higher values of capacitors and ESR could improve output stability. So the ESR could improve output stability. So the 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, APE8805 regulator has internal thermal and current limiting functions designed to protect the device. It will rapidly shut off PMOS pass element during overloading or over temperature condition. . Thermal Consideration The power handling capability of the device will be limited by maximum operation junction temperature (125°C). The power dissipated by the device will be estimated by : PD = IOUT x (VIN-VOUT). The power dissipation should be lower than the maximum power dissipation listed in “ Absolute Maximum Ratings” section. 4 Advanced Power Electronics Corp.
