Internal LDO output (Typ. 5V)
IN
This pin usually gets connected to 4.7uF capacitor
I/O power supply for interface input
This pin usually gets connected to VREG5.
PS
This pin should be connected to a 3.3V power supply when you
want to use the input directly from a 3.3V series host
(microcomputer.)
-
This pin must be connected to Low level
