... THERMAL DATA Absolute maximum ratings only apply individually; they do not apply in combination. The ADP160/ADP161 can be damaged when the junction temperature limits are exceeded. Monitoring ambient temperature does not guarantee that T specified temperature limits. In applications with high power dissipation and poor thermal resistance, the maximum ambient temperature may have to be derated ...

... LDO is always in a well-defined state, whether it is enabled or not. The ADP160 is available in 15 output voltage options, ranging from 1 4.2 V. The ADP160/ADP161 use the EN pin to enable and disable the VOUT pin under normal operating conditions. When EN is high, VOUT turns on, and when EN is low, VOUT turns off ...

... Consider the case where a hard short from OUT to ground occurs. At first, the ADP160/ADP161 current limits so that only 320 mA is conducted into the short. If self-heating of the junction is great enough to cause its temperature to rise above 150°C, thermal shutdown activates, turning off the output and reducing the output current to zero. As the junction temperature cools and drops below 135° ...

... A PCB LAYOUT CONSIDERATIONS Heat dissipation from the package can be improved by increasing the amount of copper attached to the pins of the ADP160/ADP161. However, as listed in Table 8, a point of diminishing returns is reached eventually, beyond which an increase in the copper size does not yield significant heat dissipation benefits. ...
