... L Vertical sensitivity 5mV/div. LM137-LM237-LM337 The LM137 specification is 0.02 %/W max.In figure 1, a typical LM337’s output drifts only 3mV for 0.03 – 10V) when a 10W pulse is applied for O 10ms. This performance is thus well inside the spe- cification limit of 0.02%/W x 10W = 0.2% max. When the 10W pulse is ended the thermal regulation again shows a 3mV step as the LM137 chip cools off ...
