How can I select the voltage regulator for MPC56xx

Hi, everyone

I'm a H/W Engineer for automotive.

 

My question is just one thing.

 

1. When I calculate the maximum current consumption for MPC56xx, It is approximately 300mA.

    In automotive, I should consider that ambient temperature and battery voltage at least 16V.

    I want to use the LDO, Linear Regulator for supply voltage to MPC56xx.

    but, I can't.

   There is no LDO that maximum current is up to 300 mA when ambient temperature 85℃ and battery voltage 16V.

   What is the best way to operating the MPC56xx ? LDO or Buck converter or other ?

   Can you give me some recommendations ?
