SG7900A/SG7900 SERIES
-15V NEGATIVE REGULATOR
ELECTRICAL SPECIFICATIONS (Note 1)
(Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG7915A/SG7915 with -55°C ≤ TA ≤ 150°C,
VIN = -23V, IO = 500mA for the K and IG -Power Packages-, IO = 100mA for the T and L packages, CIN = 2µF, and COUT = 1.0µF. Low duty cycle pulse
testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
