Just to add, from what I believe the TPS73633DBVT voltage regulator changed the following:
It did not helped at all with its lower dropout voltage as it shuts down by the low voltage triggering (Enable pin of the LDO) when battery gets low.
So if I needed to extend the battery life I would had to mod the output of the "enable" output - I think.
As soon as the "enable" voltage gets low and the Torex LDO would start giving buzzing the TI LDO now shuts down.


So, it is far easier, safer and cost efficient to just replace the cover of the camera to a new bigger type and the battery to a 502030 (which fits with the help of the bigger case) or 602035 (which I wait to see if it fits).
