SN6507: SN6507 huge current

Part Number: SN6507

Hello Team,

I'm an intern, trying to use the SN6507 to stabilize a variable input (between 18-30V with 24V nominal) to 24V. The only problem is that my setup is pulling a lot of amps (2A+). I have found this problem in both real life and simulations. Am I missing something? 

I have a similar setup for 24 to 3V3 that works perfectly. If I replace the 750319697 transformer with the 750320325 transformer, my output will be a stable 3V3.

Are you able to find the problem with my setup? I've added my simulation files, in case it helps

 

Best regards,

Arvid
