I am using SRF-300CA-11440 DC motor in my application. ( 6V max ) (Datasheet for DC motor)

For motor driving purpose I am going to use L293D dc motor driver chip. L293D datasheet suggests "The L293D is designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V"

So is there any problem while operating SRF-300CA-11440 DC motor on 5 Volts.

Can we use L293D for such low voltage motor driving.

Thanks in advance.


Indeed the L293D can work at 5V but a 5V regulator should be added to avoid that the current pumped by the motor decrease the voltage below the the 4.5V where the "brain" of the L293 is not activated.
