So is an external regulator a necessary precaution? Just curious...

Hi Gareth,

maybe you don't need an external regulator ?!?!

But, the specs also say that rating of supply voltage is "-0.3 to +7V".
Do you know what happens to the sharp if supply voltage rises above +7V ???
(the mux has a supply voltage of +9V for example)

Check it out and let us know at which voltage you fried your sharp.
(just kidding)

I prefer adding a voltage regulator i know the specs of.

BTW there must be a reason for recommending an operating supply voltage of
4.5V to 5.5V i guess.

Regards,

Rainer

Hi all, It seems I missed this thread... (...) As suggested by Rainer, if you use an external battery everything is much simpler, you could even use a 4.5V battery to avoid regulator. (...) I don't think you can improve this circuit with a simple (...) (23 years ago, 10-Oct-01, to lugnet.robotics.rcx)
