5. Thermal consideration

The AME1084 series contain thermal limiting

circuitry designed to protect itself for over-

temperature conditions. Even for normal load

conditions, maximum junction temperature

ratings must not be exceed. As mention in

thermal protection section, we need to con-

sider all sources of thermal resistance be-

tween junction and ambient. It includes junc-

tion-to-case, case-to-heat-sink interface and

heat sink thermal resistance itself.

Junction-to-case thermal resistance is speci-

fied from the IC junction to the bottom of the

case directly below the die. Proper mounting

is required to ensure the best possible ther-

mal flow from this area of the package to the

heat sink. The case of all devices in this se-

ries is electrically connected to the output.

Therefore, if the case of the device must be

electrically isolated, a thermally conductive

spacer is recommended.
