(1) Test conditions unless otherwise stated: VIN - VOUT = 5V, IOUT = 0.5A, PMAX = 20W, IMAX = 1.5A (2) Regulation is measured at constant junction temperature, using pulse testing at a low duty cycle. Changes in output voltage due to heating effects are covered under thermal regulation specifications. Load regulation is measured at 1/ 8” below the base of the package on the output pin. (3) VMAX = 40V for LM137, IP137, LM137A, IP137A VMAX = 50V for LM137HV, IP137HV, LM137AHV, IP137AHV |
