Voltage on the RF transmitter

Fredrick

What is the maximum voltage I can have on the VDD pin on the Parallax 433.92 MHz RF Transmitter (#27980)
In my current project my +5V source is 5.3 volts is that to much?

Mikerocontroller

This is what the data sheet says:


Electrical:
Power: +5 VDC +/- 0.250 VDC

Fredrick

What data sheet? link?

Fredrick

On the link it says
5V +/- 10%

So that mean 4.5 to 5.5 volts or is it 4.75 to 5.25volts?

So in my case whit the Part#27980 the voltage range is 4.5 to 5.5 volt, right?
So 5.3 volts is OK in my project then, right?

Part#27980

· Sorry I referenced the wrong data sheet.· Did you ask Tech Support?· I know the ad copy reads +/- 10% tolerance but of course thats not the data sheet.· Good luck.

I chased this down too. It wants 5vdc.
