Set / Adjust Output CLAMP Voltage at LTC4380


To improve current design to automotive grade, I need to redesign power supply input stage (currently designed with LT4356-Type  is not on the ARPL  11-Mar-2019)  with  LTC4380-Type.

With the LT4356 is possible to adjust CLAMP – Level (MOSFET act like LDO).

How I can do the same with LTC4380?

My voltage maximal level on output is 18 Volt (automotive application).

Thanks in advance!
