ELECTRI CAL CHARACTERISTICS
Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG7812A / SG7812 with -55°C < TA <
125°C, VIN = 19V, IO = 500mA for the K, G and IG – Power Packages, IO = 100mA for the T and L packages, CIN = 0.33F, and COUT =
0.1F. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient
temperature.
