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_A (ambient temperature) is P_D(max) = T_J(max) – T_A / θ_JA. 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.
