APPLICATION INFORMATION
INPUT-OUTPUT CAPACITORS Linear regulators require input output capacitors maintain stability. Input capacitor 10µF with 10µF aluminum electrolytic output capacitor recommended. POWER DISSIPATION AIC1117A obtains thermal-limiting circuitry, which designed protect device against overload condition. continuous load condition, maximum rating junction temperature must exceeded. important more attention thermal resistance. includes junction case, junction ambient. maximum power dissipation AIC1117A depends thermal resistance case circuit board, temperature difference between junction ambient air, rate airflow. rate temperature rise greatly affected mounting configuration PCB, board material, ambient temperature. When mounting with good thermal conductivity used, junction temperature will even when large power dissipation applies. power dissipation across device IOUT (VIN-VOUT). maximum power dissipation
PMAX (TJ-max
Where TJ-max maximum allowable junction temperature (125°C), ambient temperature suitable application. general rule, lower temperature better reliability device mounting should provide maximum thermal conductivity maintain device temperature.
