Note 3. Operation at high input voltages is dependent upon load current. When
(transient) (Note 3)
2
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.
