[x] Add LM7480-Q1 to the Altium component library.
[x] Calculate inrush current through fets for ~1500uF capacitive load, and add inrush limiting circuit if needed.
[x] Calculate max power dissipation on all fets:
1. System VCC
2. 12V supply
3. 24V supply

The required max inrush current is set to 5A and the calculated gate capacitor is CdVdT = 6uF

POWER DISSIPATION:

Dissipation is not critical but on 24V rail, additional not populated FET will be placed parallel to Q2
