Re: ir rx tip

["Dan" <dtoma@xxxxxxx>]

Hi Frank,

I get the best results without an IC regulator... let the receiver himself
to stabilize the voltage..
Usually the regulator output something around 4.7-4.8V and sometimes is not
enough for the receiver to work properly.

Look at the schematics on my site.

Best regards,
Dan

receivers
and may at some stage have the following problem.. I have been building
some
FirM Rx Units and noticed while testing that with some the Busy output was
flashing briefly and quite often as  if ir was being received...First
covered the ir reciever to block any stray ir but no good...replaced the ir
receiver still no good replaced all caps and ic ........and was ready to
take all my ir receivers back to my supplier to say they were faulty and
thought i would try the little 5v 100mA regulator and bingo the fault
cleared replace the regulator on another board and the fault also
cleared...Im not sure why the glitches were getting on the rx line unless
maybe  noise..........so watch those pesky little regulators ..........
