Output voltage temperature coefficient is ∆VOUT(worst case)+(TJ(max)-TJ(min)) where TJ(max) is +125°C and TJ(min) is 0°C. 2. VDO=VIN-VOUT when VOUT decreases to 99% of its nominal output voltage with VIN=VOUT+1V. For output voltages below 2.25V, dropout voltage is the input-to-output voltage differential with the minimum input voltage being 2.25V. Minimum input operating voltage is 2.25V. 3. IGND is the quiescent current. IIN=IGND+IOUT. 4. VREF≤VOUT≤(VIN-1V), 2.25V≤VIN≤16V, 10mA≤IL≤1A.
