L293D current draw

Hi all
I have a L293D motor driver shield of this type: Arduino Playground - AdafruitMotorShield .
I am supplying the arduino and the shield with separate power supplies, and was wondering, obviously the supply used for the shield is the one that powers the motors, but surely it must power the shield itself as well, so my question is: how many milliamperes does the shield itself draw?
Thanks in advance :slight_smile:

I can' t find that spec but you can measure it with a DMM when the motor is not connected.
