B.3 Power Supply
The RCM3305/RCM3315 requires a regulated 3.15 V to 3.45 V DC power source to oper-
ate. Depending on the amount of current required by the application, different regulators
can be used to supply this voltage.
The Prototyping Board has an onboard +5 V switching power regulator from which a
+3.3 V linear regulator draws its supply. Thus both +5 V and +3.3 V are available on the
Prototyping Board.
The Prototyping Board itself is protected against reverse polarity by a diode at D1 as
shown in Figure B-3.
