Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. Electrical specifications 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.
3. Devices are ESD sensitive. Handling precautions recommended.
4. Guaranteed by design.
5. Minimum on-time before automatic cycle skipping begins.
