Note 1: Unless otherwise specified, these specifications apply 55C
≤ Tj ≤ +150C for the LM137, 0C ≤ Tj ≤ +125C for the LM337; VIN VOUT = 5V; and IOUT
= 0.1A for the TO-39 package and IOUT = 0.5A for the TO-3, SOT-223 and TO-220 packages. Although power dissipation is internally limited, these specifications
are applicable for power dissipations of 2W for the TO-39 and SOT-223 (see Application Hints), and 20W for the TO-3, and TO-220. IMAX is 1.5A for the TO-3,
SOT-223 and TO-220 packages, and 0.2A for the TO-39 package.
Note 2: Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to heating effects are
covered under the specification for thermal regulation. Load regulation is measured on the output pin at a point 18" below the base of the TO-3 and TO-39 packages.
Note 3: Selected devices with tightened tolerance reference voltage available.
