Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. Devices are ESD sensitive. Handling precautions recommended.
4. P D(max) = (T J(max) – T A ) ÷ θ JA , where θ JA , depends upon the printed circuit layout. See “Applications Information.”
5. Specification for packaged product only.
6. V DO = V IN – V OUT when V OUT decreased to 98% of its nominal output voltage with V IN = V OUT +1V. For output voltages below 1.75V, dropout voltage
specification does not apply due to a minimum input operating voltage of 2.25V.
7. I GND is the quiescent current. I IN = I GND + I OUT .
