[SOLVED] 3.3V regulator circuit with minimum ripples on load

[mathespbe]

Hi all...

I need a regulator circuit that should give ripple as minimum as possible on load.
I'm currently having a RPS which gives 600mV peak to peak ripples as i monitored on scope.
It making my ADC value to get oscillate around +/-32.
Can someone help me???

Thanks for your reply.
It seems good while the noise is around 200mV. But I need some more noiseless. I expect the output noise in the range of 100mV or less. Is there any other options available?

Huh?
The tps73633 datasheet says it's noise is typically 30uV.

30uV is no load ripple. on Load regulation it was mentioned 200mV...

Thank you for your info godfreyl. And sorry I was mistakenly took dropout voltage as noise voltage.
Can you please give me circuit for tps73633

I need the current output upto the range of 3A. I've selaected LM1085. Thanks for your reply friends...
