Other Parts Discussed in Thread: TL1963A, TPS7A45
Some TI's LDO have NR pin to achieve low noise performance such as TPS7A47. However its noise reduction at low frequency area is a little weak. For example, LT1963A has flat noise spectral density with level less than 0.1uV/rtHz at low frequency area. If customer is interested in noise at low frequencies, do we have better way to achieve low noise at also low frequency with our LDO which has NR pin?
Or is it better to introduce TPS7A45 or TL1963A in that case?
