advanced power electronics corp. pin descriptions pin symbol 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 1f to 10f is sufficient. the output supplies power to loads. the output capacitor is required to prevent output voltage from oscillation. the ape8800 is stable with an output capacitor 1f 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. gnd vout ape8800 3 block diagram vin pin description common ground pin figure 2. block diagram of ape8800 error amp current limit thermal shutdown _ + vref 1.2v vin vout gnd rsen pmos r1 r2
advanced power electronics corp. application information output & input capacitor protection features thermal consideration ape8800 4 the ape8800 series are low dropout linear regulators that could provide 300ma output current at dropout voltage about 300mv. besides, current limit and on chip thermal shutdown features provide protection against any combination of overload or ambient temperature that could exceed junction temperature. the ape8800 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 tant- alum) 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 30m to 50m esr range betw- een device outputs to ground for transient stability. the ape8800 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. in order to prevent overloading or thermal cond- ition from damaging the device, ape8800 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. the power handling capability of the device will be limited by maximum operation junction temperature (125c). the power dissipated by the device will be estimated by p d =i out x(v in -v out ). the power dissipation should be lower than the maximum power dissipation listed in ?absolute maximum ratings? section.
