FAN1587A Datasheet, PDF (9/14 Pages) Fairchild Semiconductor – 3A Adjustable/Fixed Low Dropout Linear Regulator

FAN1587A
Junction-to-case thermal resistance is specified from the IC
junction to the bottom of the case directly below the die. This
is the lowest resistance path for heat flow. Proper mounting
ensures the best thermal flow from this area of the package to
the heat sink. Use of a thermally conductive material at the
PRODUCT SPECIFICATION
case-to-heat sink interface is recommended. Use a thermally
conductive spacer if the case of the device must be electri-
cally isolated and include its contribution to the total thermal
resistance. The cases of the FAN1587A series are directly
connected to the output of the device.
