B.3 Power Supply
The RCM3100 requires a regulated 3.3 V ± 0.15 V DC power source to operate. Depend-
ing on the amount of current required by the application, different regulators can be used
to supply this voltage.
The AC adapter supplied with the RCM3100 Development Kit provides 12 V at up to 1 A
as the input to the voltage regulator on the Prototyping Board. 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 Shottky diode at D2
as shown in Figure B-3.
