*The maximum package power dissipation must be observed.

**Reference Figure 14 for switched−battery ENABLE application.

***Depending on thermal properties of substrate, RqJA = RqJC + RqCA.

†During the voltage range which exceeds the maximum tested voltage of VIN, operation is assured, but not specified. Wider limits may apply.

Thermal dissipation must be observed closely.
