POSITIVE FIXED VOLTAGE REGULATOR

Microsemi Corporation 

SG7800A/SG7800 SERIES

12V POSITIVE REGULATOR

ELECTRICAL SPECIFICATIONS (Note 1)

(Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG7812A/SG7812 with -55°C ≤ TA ≤ 150°C,

VIN = 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.)
