Note A. Junction Temperature Calculation: TJ = TA + (PD x JA). Note B. The above numbers for JC are maximums for the limiting thermal resistance of the package in a standard mounting configuration. The JA numbers are meant to be guidelines for the thermal performance of the device/pc-board system. All of the above assume no ambient airflow.

CHARACTERISTIC CURVES
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 inputoiutput 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.
