Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. The maximum allowable power dissipation of any T
4. Response time defined as the minimum hold-off time after the LowQ™ command before applying load transients.
IN
allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
