Analog Microelectronics, Inc. AME1085 3A Low Dropout Positive Voltage Regulator 5. Thermal consideration The AME1085 series contain thermal limiting cir- cuitry designed to protect itself for over-tempera- ture conditions. Even for normal load conditions, maximum junction temperature ratings must not be exceed. As mention in thermal protection section, we need to considerall sources of ther- mal resistance between junction and ambient. It includes junction-to-case, case-to-heat-sink in- terface and heat sink thermal resistance itself. Junction-to-case thermal resistance is specified from the IC junction to the bottom of the case directly below the die. Proper mounting is re- quired to ensure the best possible thermal flow from this area of the package to the heat sink. The case of all devices in this series is electri- cally connected to the output. Therefore, if the case of the device must be electrically isolated, a thermally conductive spacer is recommended.
