Two components I believe are voltage regulators:
0954
kaaa
and

89ab kaaa
or
89a8 kaaa
One or both might be LM2936MP-5.0NOPB
Datasheet has "KAAA" in the packaging info under device marking
Is there a datasheet or way to know if either component is the LM2936?

Usually half of the SMD code is date and manufacture location, so "kaaa" might be the whole part number. To know for sure that this is the 2936, I'd remove one and compare it electrically with this kaaa. Ohmmeter between pins will be very close if the same batch/manufacturer, and close if same chip but different manufacturer. Obviously this doesn't work in all cases, but it can help in a pinch.
