Maximum Power DissipationNote 2
Notes:
  1. The device is not guaranteed to function outside its operating ratings.
  2. PD(MAX) = (TJ(MAX) – TA)/θJA, where θJA depends on the printed circuit layout. See the Applications Information section.

Notes:
  1. Specification for packaged product only.
  2. VDO = VIN – VOUT when VOUT is decreased to 98% of its nominal output voltage with VIN = VOUT + 1V. For output voltages below 2V, dropout voltage specification does not apply due to a minimum input operating voltage of 3V.
  3. IGND is the quiescent current. IIN = IGND + IOUT.
