Furthermore, both line and load regulation are better than standard fixed regulators. In addition to having higher performance than fixed regulators, the device includes on-chip current limiting, thermal-overload protection, and safe-operating-area protection. All overload protection remains fully functional if the ADJUST terminal is disconnected. Normally, no capacitors are needed unless the device is more than six inches from the input filter capacitors, in which case an input bypass capacitor is needed. An optional output capacitor can be added to improve transient response. The ADJUST terminal can be bypassed to achieve high ripple-rejection ratios, which are difficult to achieve with standard three-terminal regulators.

www.ti.com APPLICATION INFORMATION LM317M R 1 240 Ω IAdj R 2 Adjust C i (Note A) 0.1 µF C O (Note B) 1.0 µF VI VO (Note C) NOTES: A. C i 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. C O improves transient response, but is not needed for stability. C. V O is calculated as shown: Because IAdj typically is 50 µA, it is negligible in most applications. D. C ADJ 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 possiblility 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.
