... When the junction temperature drops below 135°C, the output is turned on again and output current is restored to its nominal value. Consider the case where a hard short from OUT to ground occurs. At first the ADP1710/ADP1711 current limits, so that only 270 mA is conducted into the short. If self heating of the ...

... THERMAL CONSIDERATIONS To guarantee reliable operation, the junction temperature of the ADP1710/ADP1711 must not exceed 125°C. To ensure the junction temperature stays below this maximum value, the user needs to be aware of the parameters that contribute to junction temperature changes. These parameters include ambient temperature, power dissipation in the power device, and thermal resistances between the junction and ambient air (θ ...

... CONSIDERATIONS Heat dissipation from the package can be improved by increasing the amount of copper attached to the pins of the ADP1710/ ADP1711. However, as can be seen from Table 5, a point of diminishing returns eventually is reached, beyond which an increase in the copper size does not yield significant heat dissipation benefits. ...
