(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 bottom of the package. (3) VMAX = 40V for LM117, IP117, LM117A, IP117A, LM317, IP317, LM317A, IP317A VMAX = 60V for LM117HV, IP117HV, LM117AHV, IP117AHV, LM317HV, IP317HV, LM317AHV, IP317AHV |
