Claim:
1. A switching element circuit comprising: (a) an output transistor having a control input, a source lead connected to a power supply, and an output; (b) an output stage amplifier having a control input, a source lead connected to the power supply, and an output connected to the control input of the output transistor; (c) switching circuitry connected between the power supply and ground and having a central node connected to the control input of the output stage amplifier, the switching circuitry controlling application of an overshoot current to the central node; (d) transistor circuitry connected between the power supply and ground, having a control input, and having a central node connected to the central node of the switching circuitry; (e) buffer circuitry having an input and an output; (f) current source circuitry connected between the power supply and ground and having a central node connected to the buffer circuitry input; and (g) additional overshoot current circuitry connected between the power supply and ground, having an input connected to the output of the buffer circuitry, and an output connected to the control input of the transistor circuitry.
