Table B-1 lists the electrical, mechanical, and environmental specifications for the
RCM3720 Prototyping Board.
B.2.3 Power Supply
The RCM3700, RCM3710, RCM3720, and RCM3750 operate from a regulated 4.75 V to
5.25 V DC power source. The RCM3720 Prototyping Board only has an o5 V
linear power regulator.
The RCM3720 Prototyping Board itself is protected against reverse polarity by a Shottky
diode at D1 as shown in Figure B-13.
