ELECTRICAL CHARTACTERISTICS
(Note 1)
Note 1. All regulation tests are made at constant junction temperature with low duty cycle testing.
2. This test is guaranteed but is not tested in production.
-15V & -18V NEGATIVE REGULATOR
SG120-15
(Unless otherwise specified, these specifications apply over full operating ambient temperatures for SG120-15 with -55°C
≤
T
≤
150°C, and
V
= -20V, I
= 5mA, C
= 2.0mF, C
OUT
= 1.0mF. Low duty cycle pulse testing techniques are used which maintains junction and case temperature equal
to the ambient temperature.)
