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 = 10W, 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 LM137, IP137, LM137A, IP137A
VMAX = 50V for LM137HV, IP137HV, LM137AHV, IP137AHV
