Schematic or Bill of Materials for pHAT DAC

I am going to use the pHAT DAC board for a non-Raspberry PI application. I don’t have a readily available 5V source to power the PCM5102 Charge pump supply. Can you supply a schematic or BOM so I can tell what voltage I can apply to you voltage regulator?
Thank you


The 3.3v LDO we use doesn’t have a particularly useful range of input voltages, but you can find the datasheet here:

Yep, not too useful.
Thank you for your help.
