That particular regulator can have different pinouts. I have been bitten
before. So double check that based on the supplier.
What voltage are you seeing on the output? I believe the best you can get
out of that regulator without a big heatsink is maybe 500mA which is
borderline for the BBB. You

OK. Then what you are describing as your issue, i would expect to happen.

Because the IC can't provide the required current without a heat sink? Or
because the BBB is going into thermal protection? A little insight into why
you would expect that would be appreciated.

Because the regulator is going into thermal limit due to excessive heat
dissipation. Make the 11.7V supply say 8V and it will run longer. The hole
in the tab of the regulator is for the heat sink.
Now, if the regulator is putting out 7V, then it could be the board.

11.7V supply shouldn't be a problem because it can take up to 25V, but I'll
try a heat sink and see if that helps.

This is a linear regulator. Very old technology. A watt waster. It
is dissipating the difference between the input voltage and the
output voltage. That creates a lot of heat.

in hopes of explaining what is being talked around is this. You want 5V
from 11V so there's 6V difference. Those linear regulators will give you
the 5V at some current level(let's say 1A for simplicity). So you get 5V at
1A and that's 5Watts(5V*1A) but that 1A of current is also involved

I am building a robot that uses an 11.7V battery. I tried attaching a 5V
regulator to the T5(+)/T8(-) (pins with the T6(SENSE) bridged to T5 and a
10K resistor between T8(TS) and ground. The board only stays on for about
thirty seconds then shuts down. Is it because of the TS? What type of
Can you share a schematic with me? I can't visualize what you are doing.
