Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J (MAX)
, the junction-to-ambient
thermal resistance
JA
, and the ambient temperature T
A
. The
maximum allowable continuous power dissipation at any
ambient temperature is calculated by P
D (MAX)
= (T
J
(MAX)
-T
A
)/
JA
.
Exceeding the maximum allowable power dissipation will cause
excessive die temperature, and the regulator will go into
thermal shutdown. Internal thermal shutdown circuitry protects
the device from permanent damage.
3) The device is not guaranteed to function outside of its operating
conditions.
4) Measured on JESD51-7, 4-layer PCB.
