Other Parts Discussed in Thread: LP5912,
1) I’m used to seeing a spectral noise density plot and would like to compare noise performance of this vs. the LP5912. Does TI have a plot for the TPS73501, or is there a way to translate the data to make an orange to orange comparison.?
2) Section 9.2.2.1 recommends using smaller resistors to minimize noise, but has a note about 2uA current which is a resistor >1.7Meg. Is that note there just to state if you use something less than 1.7Meg, you will perform better than the fixed version? That is, it does not imply using a 1.7Meg network, does it?
3) Also in 9.2.2.1 the datasheet states a max recommended cap to be 10nF. Is that referring to the Cnr cap, or the output cap? Section 9.2.1.1 mentions using a cap >2uF.
4) Section 9.2.1.2 requires a Cff for stability. For the feedback network = 250k, Cff is 3pF-1nF. I plan to use a network around 10kohm. How does the Cff range change? Is it just scalable?
