FAN1589 Fairchild Semiconductor, FAN1589 Datasheet - Page 7

• Manufacturer Part Number: FAN1589
• Description: 2.7A/ 1.2V Low Dropout Linear Regulator for VRM8.5
• Manufacturer: Fairchild Semiconductor

PRODUCT SPECIFICATION
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
case-to-heat sink interface is recommended. Use a thermally
conductive spacer if the case of the device must be electrically
isolated and include its contribution to the total thermal
resistance. The case of the FAN1589 is directly connected to
the output of the device.
