Notes:
1. Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical speci ? cations do not apply when operating
the device outside of its operating ratings. The maximum allowable power dissipation is a function of the maximum junction temperature, T J(Max) , the
junction-to-ambient thermal resistance, θ JA , and the ambient temperature, T A . The maximum allowable power dissipation will result in excessive die
temperature, and the regulator will go into thermal shutdown. The θ JA of the power SOT23-5 is 220°C/W mounted on a PC board.
2. The device is not guaranteed to function outside its operating rating.
3. V EN must be ≤ V IN .
4. Devices are ESD sensitive. Handling precautions recommended.
5. The maximum suggested value of the programming resistor, whose series resistance is measured from feedback to ground, is 124k ? . Use of larger
resistor values can cause errors in the output voltage due to the feedback input bias current.
