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 base of the package on the
output pin.
(3)
VMAX = 40V for LM137, IP137, LM137A, IP137A
VMAX = 50V for LM137HV, IP137HV, LM137AHV, IP137AHV
