Electrical Characteristics—LM1577-ADJ, LM2577-ADJ (Continued)
Note 8: Junction to ambient thermal resistance with approximately 1 square inch of pc board copper surrounding the leads. Additional copper area will lower thermal
resistance further. See thermal model in “Switchers Made Simple” software.
Note 9: If the TO-263 package is used, the thermal resistance can be reduced by increasing the PC board copper area thermally connected to the package. Using
0.5 square inches of copper area,
θJA is 50C/W; with 1 square inch of copper area, θJA is 37C/W; and with 1.6 or more square inches of copper area, θJA is 32C/W.
