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 TA (ambient temperature) is PD(max) = TJ(max) – TA / θJA. Exceeding the maximum
allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
4. Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal value measured at 1V
differential. For outputs below 2.25V, dropout voltage is the input-to-output differential with the minimum input voltage 2.25V.
5. Turn-on time is measured from Ven=1V of the positive edge of the enable signal to 90% of the rising edge of the output voltage of the regulator.
