Although power dissipation is internally limited, these specifications are applicable for power dissipation of : • 2W for TO-39 • 15W for TO-220 • 20W for TO-3 Package IO(max) is : • 1.5A for TO-3 and TO-220 • 0.5A for TO-39 2. Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in out- put voltage due to heating effects are covered under the specification for thermal regulation. LM137-LM237-LM337 4/14 |
