These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(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 rated operating conditions.
(2) The maximum allowable power dissipation is a function of the maximum junction temperature, T
J
(MAX), the junction-to-ambient thermal
resistance, θ
J–A
, and the ambient temperature, T
A
. The maximum allowable power dissipation at any ambient temperature is calculated
temperature, and the regulator will go into thermal shutdown. See Application Hints for additional information on heatsinking and thermal
resistance.
(3) When used in dual-supply systems where the regulator load is returned to a negative supply, the output voltage must be diode-clamped
to ground.
(4) May exceed the input supply voltage.
(5) Human body model, 200 pF discharged through 1.5 kΩ.
