Buffer Type Description
Power
Low drop-out regulator output voltage. This
pin requires an external capacitor between
the pin and GND of 1 µF or greater. When the
on-chip LDO is used to provide power to the
logic, the LDO pin must also be connected to
the VDD25 pins at the board level in addition
to the decoupling capacitor(s).
