Post by rf_jay on Aug 10^th, 2007, 5:23am

Hi,

I am now looking into designing LOW NOise, 25uV rms in 10Hz to 100kHz. LDO.
kindly suggest me the low noise technique. also docs/pdfs

thanks in advance.

Hi,

You may try to generate a low noise bandgap voltage first. Otherwise, the output noise of this LDO will be dominated by the noise from bandgap voltage, especially in the range of flicker noise.
