Dual +3.3v/+5.0-6.0v Power Supply For Servos and IMU
Posted: Sun Dec 24, 2006 9:08 pm
Can someone point me to a circuit which can be put on a small PCB that can take unregulated 11.1v power from a lithium polymer battery and regulate it down to one output of +3.3v and one output of at least +5v to a maximum of +6v. In other words, a regulator capable of producing two different voltage outputs.
The +3.3v output will be connected to an inertial measurement unit. This is just a PCB with two ICs.
The +5 to +6v output will be connected to two servos. Both are GWS brand S03N 2BB units modified for continuous rotation.
I am comfortable soldering a PCB. Perhaps there is a kit that can fill this need? I'm still learning how to read circuit diagrams, but I should be able to manage them.
As a related question, will the current draw from the servos starting up and then running really be a lot? Would it interfere with the 3.3v output, causing a voltage drop?
Thanks
Bob
