Pin Name
Pin Number Pin Type Buffer Type^a Description
LDO
E3
-
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).
