#113295 - 7 AAAs better than one block

I am making a new small dsPIC based for my new hand held weld chekers the only cable coming in is Rogowski coil shielded two core cable. no other cable enter or exit this system.

This sounds good! So, make the analog ground plane the one who says hello to the outer world.

I am planning to use LM2937 LDO can this handle complex loads.

Looks so. Give it a try.

Take care, quiescent current drastically increases, when input voltage drops below 7.5V! So, it's better to use 7 single NiCd-cells (AAA) than one 7.2V block.
