Ci is not required, but is recommended, particularly if the regulator is not in close proximity to the power-supply filter capacitors. A 0.1- µF disc or 1-µF tantalum provides sufficient bypassing for most applications, especially when adjustment and output capacitors are used. B. CO improves transient response, but is not needed for stability. C. VO is calculated as shown: Because IAdj typically is 50 µA, it is negligible in most applications. D. CADJ is used to improve ripple rejection; it prevents amplification of the ripple as the output voltage is adjusted higher. If CADJ is used, it is best to include protection diodes. E. If the input is shorted to ground during a fault condition, protection diodes provide measures to prevent the possibility of external capacitors discharging through low-impedance paths in the IC. By providing low-impedance discharge paths for CO and CADJ, respectively, D1 and D2 prevent the capacitors from discharging into the output of the regulator.
