SNVS780E May 1998 – December 2016 LM337L
PRODUCTION DATA.
The input supply to the LM337L 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 LM337L in regulation. TI recommends an input capacitor, especially when the input pin is placed more than 4 in. away from the power-supply filter capacitor.
