Note: Exceeding these ratings could cause damage to the device. All voltages are with respect to Ground. Currents are positive into, negative out of
specified terminal
.
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-
output differential increases beyond 30V. Note also from figure 1, that maximum load current is reduced at high voltages. The 50V input rating of the
SG78xxA series refers to ability to withstand 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.
