† Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the device at those or any other conditions above those indicated
in the operational sections of this specification is not intended.
Exposure to maximum rating conditions for extended
periods may affect device reliability.
‡ Notice: The device is not guaranteed to function outside its operating ratings.
Note 1: The maximum allowable power dissipation of any T
A
(ambient temperature) is P
D(max)
= (T
J(max)
– T

)/
JA
.
Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the reg-
ulator will go into thermal shutdown.
2: Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5 k in series
with 100 pF.
