SNVS778E May 1999 – January 2016 LM137 , LM337-N
PRODUCTION DATA.
The input supply to the LM137 and LM337-N must be kept at a voltage level such that its maximum input to output differential voltage rating is not exceeded. The minimum dropout voltage must also be met with extra headroom when possible to keep the LM137 and LM337-N in regulation. TI recommends an input capacitor, especially when the input pin is placed more than 4 inches away from the power-supply filter capacitor.
