(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 the junction of the wide and narrow portion of the output lead. (3) VMAX = 40V for LM117, IP117, LM117A, IP117A VMAX = 60V for LM117HV, IP117HV, LM117AHV, IP117AHV |
