Electrical Characteristics
Electrical Characteristics
Unless specified, these specifications apply over the operating ambient temperatures for SG7805A /
SG7805 with -55 °C ≤ TA ≤ 125 °C, VIN = 10 V, IO = 500 mA for the K, G, and IG – Power Packages,
IO = 100 mA for the T and L packages, CIN = 0.33 μF and COUT = 0.1 μF. Low duty cycle pulse testing
techniques are used, which maintains junction and case temperatures equal to the ambient temperature.
