Change Voltage Regulator Foot Print on PCB (Arduino Code)

I have a project for a watt meter that measures voltage, amps, amp hours, watts...

The project has also a speed reading function via GPS and some more features but the main problem to deal with is that the existing voltage regulator is expensive and hard for me to solder so it gives alot of problems.

I would like to change it to this component instead:

and of course that all the components that are related to it need to be changed/made sure they fit the new component.

The unit should be limited to 120V and now with the new component should be limited to 100V instead.

When the unit detects over 100V it should power off/not turn on if it's off.

Also, for some weird reason, the last update of the PCB didn't include an earth layer (ground all over the surface) so I need it to be added.

A power off protection limit should be added to protect the unit from working under 7.5V as that is the bottom limit for the input of the new voltage regulator.

Other things to make sure are coded and planned properly on the PCB are:

- Check if there is a 150A limit (there is a 150A current sensor) and how is it applied? how can the unit protect itself from burning if over 150A?

- Check if there is an input and output protection against reversed polarity and also for shorting out the positive and the negative.
