Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its rated operating conditions.
Note 2:
See circuit in Typical Applications. To ensure constant junction temperature, low duty cycle pulse testing is used.
Note 3:
All limits are guaranteed for T
J
= 25C (standard type face) or over the full operating junction temperature range of 40C to +125C (bold type face).
Note 4:
The maximum power dissipation is a function of maximum junction temperature T
Jmax
, total thermal resistance
θ
JA
, and ambient temperature T
A
. The
maximum allowable power dissipation at any ambient temperature is P
D
= (T
Jmax
T
A
)/
θ
JA
. If this dissipation is exceeded, the die temperature will rise above 150C
and the LM2931 will go into thermal shutdown. For the LM2931 in the TO-92 package,
θ
JA
is 195C/W; in the SO-8 package,
θ
JA
is 160C/W, and in the TO-220
package,
θ
JA
is 50C/W; in the TO-263 package,
θ
JA
is 73C/W; and in the 6-Bump micro SMD package
θ
JA
is 290C/W. If the TO-220 package is used with a heat
sink,
θ
JA
is the sum of the package thermal resistance junction-to-case of 3C/W and the thermal resistance added by the heat sink and thermal interface.
If the TO-263 package is used, the thermal resistance can be reduced by increasing the P.C. board copper area thermally connected to the package: Using 0.5
square inches of copper area,
θ
JA
is 50C/W; with 1 square inch of copper area,
θ
JA
is 37C/W; and with 1.6 or more square inches of copper area,
θ
JA
is 32C/W.
