Note A. Junction Temperature Calculation: T
= T
+ (P
x
θ
).
Note B. The above numbers for
θ
are maximums for the limiting thermal
resistance of the package in a standard mounting configuration.
The
θ
numbers are meant to be guidelines for the thermal
performance of the device/pc-board system. All of the above
assume no ambient airflow.
Note 3. Operation at high input voltages is dependent upon load current. When
load current is less than 5mA, output will rise out of regulation as input-
oiutput differential icreases beyond 30V. Note also from Figure 1, that
maximum load current is reduced at high voltages. The 50V input rating
of the SG140A series refers to ability to withstnd high line or transient
conditions without damage. Since the regulator's maximum current
capability is reduced, the output may fall out of regulation at high input
voltages under nominal loading.
