<It's an awesome part, along with its predecessor the LT3042 and now they 
<have negative versions of them.
<And for those that care, it's not subject to single event latchup.

<However, in? *this* application, I'm seeing big (>50V) inductive 
<transients from relays and motors, and those would be quick death for 
<those parts.? So I'm thinking I'm going to be getting some Tranzorb 
<devices (basically back to back zeners) to clamp the transient.

##  why cant  u wire a RVS  connected diode across the relays  and motor windings ? 
On paper, that should clip off the transients asap.   Then use whatever  filter  you want after that.
