Multiple power sources
hello:
I'm building a robot but I need three power sources: 6v for the servos (via PSC), 9v for de BS2 and 12v for the motors (via Motor Mind C). Is there some way to use the 12v lead-acid battery as the power source for all the components. What components I need to generate three outputs (6v, 9v and 12v) from the battery without the risk of damaging either the BS2, the PSC, the MMC or even the servos.
I was thinking in voltage regulators, but I don't know how to use them.

The LM7805 has a V_Dropout of 2 volts, I believe. The LM2940-5 is a 'low-dropout' device -- 0.5 volts is V_Dropout.
So, you can drive the MotorMind-C directly with the Lead-Acid voltage, put in a 6-volt regulator for the Servo's, and a separate 5-volt regulator for the BS2. The BS2 doesn't need 9-volts, you can supply 5-volts directly to the BS2 Vdd from an external regulator.
Oh, and you can look at the BOE schematic for a simple Linear Regulator design.
I will work on a diagram and I'll share it with you to receive your opinion.
Thank you!!!
