Equivalent part number for rf board

[G1LWX]

Hi
I am after an equivalent part number for the MIC5231-2.75YM as used
in the rf board.
The only place I can find one is Mouser or Digikey but for a one off is quite expensive.

Mike - please remind me exactly which PCB it is used on?

Hi Dave
It's off the 4 Band RF output switch board for the Portsdown.

Hi Mike

Not sure that there is a pin-for-pin replacement, but any regulator arrangement that gives between 2.5 and 2.8 volts could be used (don't be tempted to go as high as 3.3v). The current consumption is very low (less that 10 ma I think).

Dave G4FRE reports that he used a 3.3 V regulator with a diode on the output to drop the voltage.

Thanks Dave i'll sort it just wondered if there was a direct replacement. A 3.3v with a diode sounds a good idea
