ELECTRICAL SPECIFICATIONS (Note 1)
(Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG7812A/SG7812 with -55
°C ≤ T
A ≤ 150°C,
V
IN = 19V, IO = 500mA for the K and IG -Power Packages-, IO = 100mA for the T and L packages, CIN = 0.33µF, and COUT = 0.1µF. Low duty cycle pulse
testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
