Kepler Communications Sample

Some design comments,

The LDO’s charge pump can cause the output to feature noise. One way to reduce the high frequency components of the output voltage noise is by placing 10-100nF bypass caps nearest to the load. Another method would be to create a pi/EMI filter by adding a ferrite bead between the output and the load capacitors.

As for the feedback circuit layout considerations... The feedback voltage dividers needs to be as close as possible to the FB pin of both devices respectively. In the case of the LDO, the feedforward capacitor also needs to be placed closest to the FB and OUT pins.
