2 / 4 page ![]() 2 www.irf.com OM7580SC Footnotes Q- Denotes specifications which apply over the full operating temperature range. R- The minimum load current is minimum current required to maintain regulation. Normally the current in the resistor divider used to set the output voltage is selected to meet the minimum load current requirement. S- The control pin current is the drive current required for the output transistor. The control pin current is approximately 0.01% output current. The minimum value is equal to quiescent current of the device. Electrical Characteristics @TA = 25°C (Unless Otherwise Specified) Parameter Test Conditions Min. Typ. Max.
