Notes:
1. Exceeding the absolute maximum ratings may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. PD(max) = (TJ(max) – TA) / θJA, where θJA, depends upon the printed circuit layout. See “Applications Information.”
4. Device is ESD sensitive. Handling precautions recommended.
5. Specication for packaged product only.
6. VDO = VIN – VOUT when VOUT decreased to 98% of its nominal output voltage with VIN = VOUT +1V. For output voltages below 1.75V, dropout volt-
age specication does not apply due to a minimum input operating voltage of 2.25V.
7. IGND is the quiescent current. IIN = IGND + IOUT.
8. For a 2.5V device, VIN = 2.250V (device is in dropout).
