ZHCSHH4L March 2000 – January 2018 LM317L-N
PRODUCTION DATA.
The input supply to the LM317L-N must be kept at a voltage level lower than the maximum input-to-output differential voltage of 40 V. When possible, the minimum dropout voltage must also be met with extra headroom to keep the LM317L-N in regulation. TI recommends using an input capacitor, especially when the input pin is located more than 6 inches away from the power supply source.
