Electrical Characteristics (continued)
(V_VIN = +5.5V to +55V, T_AMB = -40°C to +125°C, unless otherwise noted. Typical values are at V_VIN = +14V and T_AMB =
+25°C. Positive currents flow into the device pins.)

1) For reference voltages at ADIMx below 0.6V the linearity error may scale to higher values
2) Value limited to avoid excessive current flow in VSM regulator, see also „1 Absolute Maximum Ratings“
3) Consider this parameters espesially for SEPIC or Flyback topologies
4) Not production tested
