ELECTRICAL CHARACTERISTICS (continued)

Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG7915A / SG7915 with

-55°C < T_A< 125°C, V_IN= -23V, I_O= 500mA for the K, G, and IG - Power Packages, I_O= 100mA for the T and L packages, C_IN= 2µF,

and C_OUT= 1µF. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient

temperature.
