I looked at the PCB files. To get that 12 V output you will have to cut some etch or lift pins and "blue wire" the correct pins to GND. It looks like there is only one version of that board and it is...

Noise will vary very little as device operation approaches dropout. However, PSRR will be affected is the load current is such that the device is actually operating in drop-out mode.Cff (across R1) is...

A ground plane under the device, top layer, can be used but isn't required as long as good coupling to a ground for all the GND pins. Keep the decoupling capacitors in close proximity to the power...

Yes, for LP5907 the '-3.3' suffix does indicate a fixed Vout of 3V3.Good to ask because on some devices it's not always what it obviously seems to be.A recent data-sheet bulk editing effort...

From figure 2 or 10 of SLUA612, D1 prevents pump up of the BAT pin from transients which come past the pack level TVS D9. With the R4 and C2 values, D1 could likely be a zener, but it is working...

Hi Axel, You should review the output voltage rails and see if you are ok with the ripple voltage. Then check the transient response of the rail by mimicking your load transients. If you are fine with...
