LM555 oscillator

[renju]

with 5v to LM555 , how to reduce the output to 10mV? a simple resistive attenuator will do?

 

[(*steve*)]

Yes, but we have to ask why. It's a very unusual thing to want to do.

LM555

bcos my circuit needs only mV range of sinewave...

A 555 oscillator won't give you a sine wave.

A approximation to a sine wave could be achieved by using a few stages of attenuation each stage using a series resistor and a parallel capacitor.

The effect would change if the frequency changes.
