Notes:
1.
Absolute maximum ratings indicate limits beyond which damage to the component may occur. 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
(max),
the junction-to-ambient thermal resistance,
θ
, 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.
2.
This device is not guaranteed to operate beyond its specified operating ratings.
3.
Devices are inherently ESD sensitive. Handling precautions required. Human body model.
4.
For options with OVP.
5.
Using 4 layer PCB.
6.
Specification for packaged product only.
7.
