Hi Larry,

LM317T has a 40V max input to output differential voltage, so with 5V
logic you could input 45V, which would be over adequate for a L298
design. In the UK we can buy these at around US$0.30 each. TI part
is however excellent for high voltage drives (as per G201's etc).

Hey..... you must have the same soldering iron as me ! <bigger grin>

Regards,

Paul ;-)
