Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The shaded electrical speci?cations indicate those parameters
which have been improved or guaranteed test limits provided for the ?rst
time.
Note 3: Unless otherwise indicated, these speci?cations apply: | V IN
– V OUT | = 5V; and I OUT = 0.1A for the H package, I OUT = 0.5A for the K, M,
and T packages. Power dissipation is internally limited. However, these
speci?cations apply for power dissipation up to 2W for the H package and
20W for the K and T packages. I MAX = 1.5A for the K, M, and T packages,
Note 4: Testing is done using a pulsed low duty cycle technique. See
thermal regulation speci?cations for output changes due to heating effects.
Load regulation is measured on the output pin at a point 1/8" below the
base of the K and H package and at the junction of the wide and narrow
portion of the lead on the M and T package.
Note 5: Load regulation for the LT337AT is the same as for LM337T.
Note 6: Guaranteed on LT137A and LT337A, but not 100% tested in
production.
Note 7: I SC is tested at the ambient temperatures of 25°C and –55°C. I SC
cannot be tested at the maximum ambient temperature of 150°C due to the
high power level required. I SC speci?cation at 150°C ambient is guaranteed
by characterization and correlation to 25°C testing.
and 0.2A for the H package.
