The following grounds should be routed back to their respective regulators and then tied directly to the ground plane with one
via: GND_PVSS, GND_MPVSS, GND_TPVSS, and GND_A2VSSN. The other ground pins (GND_AVSSN, GND_A2VSSQ,
GND_RSET, GND_R2SET) should be tied to the ground plane directly through one via as close to the pins as possible
without connecting to anything else. If space is an issue it is possible to use one via for two adjacent pins.
Use 47uF Tant. 16V 20% D size (P/N 4230047600),
800mR Max. ESR and Max. ripple 430mA @ 100kHz
or
100uF, Alum. 6.3V 20% 6.3mm dia (P/N 4261010700),
440mR Max. ESR and Max. ripple 230mA @ 100kHz
or
47uF, Alum. 6.3V 20% 5mm dia (P/N 4262047600),
760mR Max. ESR and Max. ripple 150mA @ 100kHz
