LM117, LM317A, LM317-N
SNVS774O –MAY 2004–REVISED JANUARY 2014 www.ti.com
Typical Applications
Full output current not available at high input-output voltages
*Needed if device is more than 6 inches from filter capacitors.
†Optional—improves transient response. Output capacitors in the range of 1 μF to 1000 μF of aluminum or tantalum
electrolytic are commonly used to provide improved output impedance and rejection of transients.
