Note 1. Exceeding the absolute maximum ratings may damage the device.

Note 2. The device is not guaranteed to function outside its operating rating.

Note 3. PD (max)= (TJ (max) - TA) ÷ θJA, where θJA -junction-to-ambient thermal resistance.

Note 4. Output voltage temperature coefficient is ΔVOUT (worst case) ÷ (TJ(max) - TJ(min)) where TJ(max) is +125°C and TJ(min) is 0°C.

Note 5. 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.

Note 6. IGND is the quiescent current. IIN = IGND + IOUT.

Note 7. Delay time is measured after VEN=VIN. CIN=COUT=10μF.

Note 8. For adjustable device and fixed device with VOUT ≥ 2.5V

Note 9. VREF ≤ VOUT ≤ (VIN - 1V), 2.25V ≤ VIN ≤ 16V, 10mA ≤ IL ≤ 1 A.
