Notes:

1. Exceeding the absolute maximum rating may damage the device.

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

3. The maximum allowable power dissipation at any TA (ambient temperature) is PD(max) = (TJ(max) – TA) / θJA. Exceeding the maximum allowable power

dissipation results in excessive die temperature, and causes the regulator to enter thermal shutdown.

4. Devices are ESD sensitive; use proper handling precautions. Human body model, 1.5kΩ in series with 100pF.

5. Specifications are for packaged products only.

6. Assure that VIN ≥ (VOUT + 3V) and VIN ≥ 6V.

7. Quiescent current is specified for the adjustable option. The fixed options will add approximately 1µA due to the internal feedback resistors.

8. Line regulation is a percentage of VOUT.
