ELECTRICAL SPECIFICATIONS
(Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG7912A/SG7912 with -55 C T
V
testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
Note 1. All regulation tests are made at constant junction temperature with low duty cycle testing.
