Note 1:
Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the de-
vice outside of its rated operating conditions.
Note 2:
The maximum allowable power dissipation is a function of the maximum junction temperature, T
(max), the junction-to-ambient thermal resistance,
θ
JA
,
and the ambient temperature, T
A
. The maximum allowable power dissipation at any ambient temperature is calculated using:
Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. See APPLICATION
HINTS for additional information on heatsinking and thermal resistance.
Note 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.
