Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which the device is func-
tional, but do not guarantee specific performance limits. Electrical Characteristics state DC andAC electrical specifications under particular test conditions which guar-
antee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit is
given, however, the typical value is a good indication of device performance.
Note 2:
Thermal resistance without a heat sink for junction to case temperature is 3C/W and for case to ambient temperature is 50C/W for the TO-220, 73C/W
for the TO-263. 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.
Note 3:
All characteristics are measured with a capacitor across the input of 0.1 μF and a capacitor across the output of 10 μF.All characteristics except noise voltage
and ripple rejection ratio are measured using pulse techniques (t
W
≤
10 ms, duty cycle
≤
5%). Output voltage changes due to changes in internal temperature must be
taken into account separately.
Note 4:
Guaranteed and 100% production tested.
Note 5:
Guaranteed (but not 100% production tested) over the operating temperature and input current ranges. These limits are not used to calculate outgoing qual-
ity levels.
Note 6:
To ensure constant junction temperature, low duty cycle pulse testing is used.
