ELECTRICAL CHATRACTERISTICS (Note 1)
SG120-20
(Unless otherwise specified, these specifications apply over full operating ambient temperatures for SG120-20 with -55°C ≤ TA ≤ 150°C, and
VIN = -29V, IO = 5mA, CIN = 2.0mF, COUT = 1.0mF. Low duty cycle pulse testing techniques are used which maintains junction and case temperature equal
to the ambient temperature.)
