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 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
