Refer to ELECTRICAL CHARACTERISTIS and APPLICATION INFORMATION for Safe Operating Area. 7. Minimum Vin = 5.5 V or (Vout_nom + 0.5 V), whichever is higher. 8. Corresponding RCSO is in range from 25 kW down to 728 W. ELECTRICAL CHARACTERISTICS Vin = 13.5 V, VEN = 5 V, RCSO = 0 W, CCSO = 1 mF, Cin = 1 mF, Cout = 22 mF, ESR = 1.5 W, Min and Max values are valid for temperature range −40°C ≤ TJ ≤ 150°C unless otherwise noted and are guaranteed by test design or statistical correlation. Typical values are referenced to TJ = 25°C.
