need 40-50ma buffer driver iCs idea

[Ron Marcus]

Try the STmicro L293D. It will drive up to 600 mA in an H bridge fashion. It is simple and rugged. It also has built in diodes for inductive loads. Available @ Digi, or Mouser. The only down side is that it's current draw is on the high side. I use them by the fist full for robotics.
