Notes
The ● denotes the specifications which apply over the full operating temperature range.
(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
