CS5205A-1

5.0 A Adjustable Linear Regulator

ON Semiconductor 

CS5205A−1

The value for RΘJA is calculated using equation (3) and

the result can be substituted in equation (1).

The value for RΘJC is normally quoted as a single figure

for a given package type based on an average die size. For

a high current regulator such as the CS5205A−1 the majority

of the heat is generated in the power transistor section. The

value for RΘSA depends on the heat sink type, while RΘCS

depends on factors such as package type, heat sink interface

(is an insulator and thermal grease used?), and the contact

area between the heat sink and the package. Once these

calculations are complete, the maximum permissible value

of RΘJA can be calculated and the proper heat sink selected.

For further discussion on heat sink selection, see application
