ELECTRICAL CHARACTERISTICS Vin = 13.5 V, VEN = 3.3 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.
