Notes :
1. Exceeding the absoulte maximum ratings may damage the device.
2. The device is not guaranteed to work outside its operating ratings.
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. Speci?cation for packaged product only.
5. Minimum input for line regulation test is set to V OUT + 1V relative to the highest output voltage.
6. Dropout voltage is de?ned as the input-to-output differential at which the output voltage drops 2% below its nominal value measured at 1V differen-
tial. For outputs below 2.25V, dropout voltage is the input-to-output voltage differential with the minimum input voltage 2.25V. Minimum input operat-
ing voltage is 2.25V.
